COMPLETE UNINSTALL OF YAHOO MESSENGER
Please note that doing a clean uninstall of Yahoo Messenger will erase your message archives so read here about how to copy them http://help.yahoo.com/l/us/yahoo/messeng…

First uninstall Yahoo! Messenger through add/remove programs.

If you want to do a total clean uninstall of Yahoo Messenger then also navigate to Program Files on your hard drive and delete the Messenger folder inside of the Yahoo Folder. Follow this path (XP): My Computer>>C: drive>>Program Files>>Yahoo>>Messenger. Reboot your computer (important!).

If you have a trusted registry scanner use it now. If you do not have a trusted registry scanner that you are familiar with than skip this step because you can mess things up if you do not know what you are doing. I personally use CCleaner but then I have been using it for years and know how to use the Registry scanner portion safely. Using any of these types of programs is USE AT YOUR OWN RISK. Make sure you know how to create a system restore point and backup any of the Registry files it changes.

It is important that now you reboot your computer. Now download and install Yahoo messenger again using the following link: Full Installer for Yahoo Messenger 9.0.0.2162
