Y!Multi Reg Patch 8/9/Beta 10 for Windows 7, Windows Vista, Windows XP
Run multiple instances of Yahoo Messenger!
This does the same as the Y!Multi Messenger program except it is a registry script. It is recommended to only use this if you can not get the Y!Multi program (http://www.download4a.com/Windows/Internet-Communication/Chat-Instant-Messengers/Download-Y-Multi-Messenger.html) to work for some reason. This will work for versions 8, 9 and Beta 10 of Yahoo Messenger.
