• Answer:

  Yahoo leaves many traces of itself in the registry when an old version is uninstalled or a new one fails to install properly - (my uninstall left close to 30 references). The new version will NOT install completely until they are cleaned out. It requires deleting all Yahoo Messenger references from the registry. (Be very careful - you could make a mess there!) WinASO is only one of many registry cleaners, but its advantage is that it allows you to be very specific about exactly what you chose to delete, making it extremely safe. The free trial version only removes 10 references at a time, so it's much work. Remember to backup the registry by creating a new Restore Point first! File Hippo has several versions of Yahoo Messenger. Download and SAVE the program directly from here - it seems less problematic than an update or install from Yahoo's site. Install it only after completely cleaning the registry of remnants. Use a search engine to find Lenny Vasbinder's column on 'How I ALWAYS Do a Clean Install Of Yahoo Messenger on XP'. It should also work for Vista and Win 7, but I don't have those. It does take a lot of time, but should be worth it. I had tried Yahoo Support Desk too, but it didn't cure my woes, alas. Take the time - hope it works for you too.
