Many other updates prior.
Quick-Steps To Summarize The Below Information:
(NOTE: Create A Restore Point before each step if you are unsure of your computer tech abilities)
1. Uninstall Yahoo Messenger (YM) using the Revo Uninstaller. Save a copy of your Archives folder if you keep archives of your chat sessions. Turn off and re-start computer.
2. Run CCleaner Registry Cleaner (or WinASO or other legitimate registry cleaner)
3. Run Secunia Online Scanner to see if it finds any OLD remnants of YM.
4. Make sure you have updated versions of Adobe Flash Player and Sun's Java browser plugins for Internet Explorer, preferably version 8 (mainly for use in the Chat Rooms, not as much for YM)
5. Download a FULL sized version of YM from FileHippo.com or your preferred download site, to your desktop or preferred download folder.
6. Turn off and re-start your computer and make sure IE is working properly, including the Java and Flash sites.
7. Go to your downloaded FULL sized version of YM and run the .EXE file to start the installation. You may not want to install any toolbars or other add-ons that Yahoo may have included in the download. DO NOT RUN YM YET.
8. Move your copy of your archive folder back to where it should be.
9. Start up YM and go through all of the Preferences Menu setting things up how you like them since the above steps would have removed all of your previous settings.
10. Start IM'ing your friends, testing all of the features and go to Chat Rooms to make sure things are working well. If they aren't, leave me a comment below or go to the Yahoo Messenger Yahoo Group (link in next paragraph), join the group and post your questions there.
Here's something that should fix the invisible IM's issue that many are seeing.
When you send/receive an instant message and no message appears, you most likely have Scripting disabled in your Internet Explorer.
To enable Scripting:
Click the Tools menu on your Internet Explorer toolbar and select Internet Options.
Click the Security tab.
Click the Internet (globe) icon and click the Custom Level button.
Scroll down to Scripting. Enable the following:
Allow paste operations via script
Scripting of Java applets are all enabled.
Click the OK button at the bottom of the window.
Please Note: Restart Messenger and you should start seeing text in your IM windows once again.
Following is a message and amendment that I posted in one of my Yahoo Groups, http://groups.yahoo.com/group/Yahoo_Messenger, back in May 2007 but I've been meaning to post it to my blog as well so here it is about five months later! And I have updated this article many times since.

Subject: How I ALWAYS install Yahoo Messenger on Windows XP
Hi YM Group,
I thought I had done this before but after someone contacted me off list, I searched through the archives and couldn't find my post so I guess I've just added bits and pieces of this information in various replies over the years but here is how I prepare my computer before downloading a new version of Yahoo Messenger (YM).
Uninstall old version of YM using Add/Remove programs for the YM uninstaller. Reboot computer. OR BETTER YET, use the Revo Uninstaller and use it's default settings to find and remove a lot of the junk that the normal YM uninstaller leaves behind. http://www.revouninstaller.com/ Go through each step and delete the files and registry keys that it highlights and recommends except you might want to save a copy of your archived chats and other archived info as mentioned later in this article.
Reboot your computer after each step in this article.
Run a GOOD registry cleaner. I use and recommend WinASO Registry Optimizer http://www.winaso.com/download.htm which is FREE to download and use as long as you like, but the trial version has a limitation that is more of an annoyance than anything else, in that it tries to get you to pay for the unlimited version but if you don't mind dealing with the annoyance, it works as good as the paid version. I've been using the FREE trial version for several years since version 1.0. I've never had a single problem using it to clean and optimize my registry. The downside/annoyance of the free trial version is that it will only clean 10 items each time it is run. The first time you run it, you may find several hundred items that need to be fixed so you will have to run it dozens of times. OR BETTER YET, you can run CCleaner's Registry Cleaner option, http://www.ccleaner.com/, to get rid of most of the junk and then follow it up with WinASO (FREE version) to do a full cleaning since it does a better job than CCleaner. After that, if you run WinASO 1-2 times a week, it will be much quicker, easier and keep your computer from being bogged up as much with junk. After cleaning/fixing your registry, reboot your computer.
Another FREE registry cleaner is offered as an online scan from Microsoft by going to the Windows Live OneCare Safety Center http://onecare.live.com/site/en-us/center/cleanup.htm and run the Clean Up scan. You will have to allow a small download for the scan to run and you may also see the new Microsoft Security Essentials advertised on that page. For an MS product, it's getting rave reviews from many in the computer tech and security industry. It's not needed to use the free scans and it's not as extensive as other FREE security software that is out there but it is an easy to use security program for folks that do not want to learn the more sophisticated security programs.
Now download and SAVE (to "desktop" or your favorite file folder for saving things where you can find the download after you reboot) the full version of Yahoo Messenger from http://www.filehippo.com/download_yahoo_messenger/ or your favorite safe program download site. DO NOT chose "RUN" during the download and DO NOT RUN or execute the full version after it is downloaded. The full version of YM is around 10-15MB (depending on which version) in comparison to the Yahoo Messenger "official" installer that is only around 484kb when downloaded from http://messenger.yahoo.com/ I find that the Yahoo installer will have more problems especially if someone has a strong firewall or slow internet connection.
It's this "installer" version that causes so many problems, IMO. Because when you run it, it then starts downloading other bits and pieces of the program and if there are any glitches in your internet service or with Yahoo servers (and we all know there are those! ;-\), you can end up with a bad download with various bugs. When you download the full version from FileHippo or another download site, after you download it and get ready to run it, there should be Publisher listed, which should be Yahoo! Inc in a blue link which is to a digital verification site to verify that you have a legitimate version of the program. This works for most programs you may download although there are many that will not have this digital verification capability and when you go to execute one of these "unsigned" programs, you will get a little warning message on the box. If I know I downloaded the program from a reliable site, I don't worry about this but if you are not sure, you should never run a program without a digital signature attached. Many other programs have a way to run a check-sum on the download to make sure you got the download in full without errors but I've never seen this available with YM. Usually, if you have the digital signature, it means things went smoothly and you have a full version without errors.
If you use CCleaner, you should run it now to clean out your temporary files and TIF files. I am not going into all the aspects of CCleaner in this post but for most folks, it can be a problem to remove things they did not want cleaned if they do not go through and become very familiar with the program. It will clean auto-complete info, search history, cookies, etc., when used in the default mode. The CCleaner Registry Cleaner is OK to use in default mode but the rest of CCleaner should be understood before running or the user could lose information that they actually wanted to keep. This is why I like WinASO as a registry cleaner. Even a rookie can run the registry optimizer without causing problems to their computer... at least it's never caused me problems in hundreds of times of running it.
If you don't use CCleaner and did not use the Windows Live OneCare Safety Center Cleanup Scan, you should use your web-browser Tools to empty the TIF files. Then run a Search on your computer for all temporary files and remove them manually. If you don't know how to do this, then you should download CCleaner and become familiar with CCleaner and use it for this purpose or use the Windows Cleanup online scan. Feel free to ask me here and I'll tell you how I have my CCleaner set up to run it daily to keep the junk files off my computer.
Reboot the computer and leave all other programs turned off except for anti-virus and firewall.
Then, if you downloaded YM full version to your desktop, simply click on it to execute the program. If you have a firewall, you should get a pop-up asking for access, from the YM program installer, to the internet and other areas of your computer. Permit this and if you use an advanced firewall (which you should be using over the Windows Firewall which isn't very good), put a check mark in the box to allow it on a permanent basis. You can always go back to the firewall user interface and delete this permission later if you want to.
Choose the "CUSTOM" install instead of Yahoo's recommended install. This makes sure that all you install is YM and not all the other junk they try to get you to install like tool bars, etc. I choose CUSTOM install on ALL programs that I install on my computer to make sure I don't install junk I didn't want. The CUSTOM install still gives you the option to install other things but it doesn't force them on you without your knowledge. This is common practice on all FREE programs as a way to help them pay for their free program. Google, MSN, Yahoo and other companies pay to have their toolbars and desktop search programs included in the downloads. Reputable download sites and programs give you the option of opting out of these add-ons.
Now, once the YM program is installed on your computer. Reboot again.
Rebooting is important to computers as it's a way of letting the computer put everything back into place. If you are in the habit of leaving your computer on for days at a time, if you find it getting sluggish, a reboot will normally speed it back up again.
Now start up YM and go through your preferences, setting things to work how you like them. Become familiar with the Messenger Menus and the Preferences Menus and ask questions here about anything you may not understand.
The last thing that I do with any new install of YM is go into the C:\Program Files\Yahoo!\Messenger folder (or for version 10.x, the Yupdater.exe is now located in C:\Documents and Settings\All Users\Application Data\Yahoo!\YUpdater and find the file Yupdater.exe and change the name to Yupdater-NOT USED.exe. You can also use your firewall to simply block Yupdater.exe from connecting to the internet but many folks do not utilize their firewalls in an advanced mode so Yupdater.exe would have access unless you went into your firewall and blocked it. This way with changing the file name, your installed version of YM will not automatically update to any newer release of YM without your express consent as YM will not find the Yupdater.exe file when it tries to contact Yahoo like it will do on a regular basis if you don't block it or change the file name. YM 10.0x does have a section in the preferences that allows you to check off saying that you do not want YM to update automatically and I have that checked off but I still change the Yupdater.exe file as well.
If you decide you are not happy with your current version, you can then repeat the steps above and download a more recent version and install that version. I've found that allowing Yupdater.exe to connect to Yahoo, it constantly stays in contact with Yahoo whenever YM is in use. I've verified this with my firewall. I'm not sure why an updater process would need to stay in constant contact with the manufacturer. Even my Antivirus, Antispyware, etc., only contacts their updates once a day for new malware definitions. None of my other programs on my computer stays in constant contact for updates. They either run on a monthly basis or some other time interval. Certainly, Yahoo isn't releasing daily updates so YM should not need 100% access to Yahoo servers, IMO.
Hopefully, if all went well, your newly installed or reinstalled version of YM will be much more stable and cause less problems for you and you will not need to update to new versions as often.
I still run YM versions 8.1x, 9.1x and 10.0x and they are very stable on my computers compared to some of the stories I read about daily and with the people I help on a daily basis here and on other forums and my friends and neighbors that used the Yahoo Installer.
I hope this helps and feel free to ask any questions you may have. I'll probably put this on my blog with some screen shots of WinASO and CCleaner and how I have my CCleaner set up so it does not clean things some people actually want to keep and I'll post a link when I do.
Ooops. I almost forgot one step. It may not be critical but it could cause you to lose your archived chats if you have YM set to save them. Before uninstalling and cleaning up your computer with Revo Uninstaller, WinASO, CCleaner and Windows OneCare Cleanup utility, for XP, go to C:\Program Files\Yahoo!\Messenger\Profiles\(your yahoo name)\Archive and copy both of the folders in the Archive folder. For Windows Vista and Windows 7, the file path is C:\Users\\AppData\Local\VirtualStore\Program Files\Yahoo!\Messenger\Profiles\. There should be a Conferences and a Messages folder. Just copy and save them to your desktop or your other favorite place to save things.
Usually, during an uninstall and reinstall of YM, using the standard uninstaller, these folders are left in place but in the past, if I had a buggy YM install, I would sometimes go and delete the entire Messenger folder (C:\Program Files\Yahoo!\Messenger) (and the AppData folder for Yahoo!\Messenger in Vista/W7) to make sure I get rid of all traces of the buggy version. By saving copies of the Archive folders, I can move them back into their proper place after a new clean install. If you go to this extreme of removing everything associated with YM, make sure you run WinASO, CCleaner and Windows OneCare Cleanup utility before doing the clean install of the new full version download.
Hope this helps!
Here are the emails that I mentioned in the May 08, 2010 Update:

Subject: I'm back!!
Thanks for the 2 sites you gave me to uninstall and check for updates, really good ones.
I did the complete uninstall and downloaded the latest IM 10.x and the scan said it was perfect, it also picked up 3 earlier versions of yahoo that are lying in my registry that uninstall has not removed. How do I identify that and erase it?
I have copied the new IM 10.x to a flash drive and am going to uninstall the sytem again and reinstall after I have erased the old Im's, as I still have the same display problem at 480 x 800 ech time I log on. Added to that, my cam works on IM, but when I choose a room it won't connect, just says getting room list and stays dead, so it's got worse damnit.
Thats why I want to start fresh again, also I now get a add on notification on any site saying website wants Adobe flash player wants to be added on. I have okayed it and run it but nothing changes the system and it keeps on appearing.
I have also checked my add ons in tools and they are all enabled.
So once again, would you kindly give me your thoughts?

Subject: RE: I'm back!!
See one of my previous replies. After you did the FULL install of YM, did you check the YahooMessenger.exe file Properties>Compatibility Tab, to make sure that you don't have a check mark in the display settings box? It shouldn't be but possibly one of your old versions has a registry key that is affecting the settings of your new download.
If that isn't the problem, I'm wondering if one of the old version or some registry remnant from one of the old version is messing things up in other ways.
Did you save the FULL download from http://www.filehippo.com/ (or your preferred download site)? If you saved it on your desktop or in a folder in your My Documents folder or however you have your computer organized, then there is no need to copy that to a flash drive. When you uninstall YM, it will not delete the file that you downloaded so after you clean things up, you can just click on that .exe file again and start the install process all over again.
When you uninstall YM 10.x, I would use the Revo Uninstaller and then follow the instructions with Revo to delete all of the leftover registry keys and program remnants. See my blog article for more details.
Then run the Secunia Online Scanner again and see if it finds any remnants of the old versions of YM. If it does, it will actually list the file path to where that remnant was found and you can just follow that file path and just highlight and delete the files. OR... after running Revo, you can just go to your C:\Program Files\Yahoo!\Messenger and delete the entire Messenger folder but you may want to go through that folder and only delete the things you do not want to keep. For example, I save my archived chats so I move those Archive folders to My Documents folder and then move them back to their proper place after I install a new version. For Windows XP, the Archive folder is in the above file path.
For Windows Vista and Windows 7, the file path is:
If you feel comfortable fooling with your Registry, you could also search for Yahoo Messenger entries in your registry and clean them out manually, although I would use CCleaner's Registry Cleaner and then WinASO Registry Optimizer to look for and clean up any errant registry entries... and if you used Revo Uninstaller, it probably already got them all!
After things are all cleaned up, then do the installation again, check the Properties>Compatibility Tab to make sure nothing is checked there and if you are still having monitor issues, I would have to think it's one of the other problems with a driver that needs to be updated or rolled back. See my earlier reply for some of the other issues that caused monitor issues related to YM.
As far as Adobe Flash, once you've uninstalled it and removed the old remnants, using the same methods above, go to http://kb2.adobe.com/cps/155/tn_15507.html and it will check your version and http://www.adobe.com/software/flash/about/ will show an animated flash video that says "Adobe Flash Player Successfully Installed" and then change to another Adobe related Ad. If you aren't updated or installed properly, go to http://get.adobe.com/flashplayer/ (you may want to uncheck the Google Toolbar thing... I NEVER install all of the add-on software that is often pushed from many free programs) Click on Agree And Install and follow the prompts to install Adobe. Prior to doing this, Secunia's Online scanner should have told you about out-dated Flash remnants and you can follow the file paths to delete the outdated flash files that were left over from previous installations.
As far as going to the rooms, I think you have to have Java installed. Did Secunia identify if you had Java installed and updated? If you didn't, get it here. http://www.java.com/getjava/ On that page, right below the Free Java Download button, there's a link to "Do I Have Java?" so you can check it first and that will also tell you if you have the latest version.
I probably need to add some of this info to my article on doing a FULL and CLEAN install of YM since Flash and Java are often needed with YM.
