I have a problem installing the yahoo messenger  9 in windows vista. We’re always a victim of software incompatibilities.They (the  software developers) tend to forget that we spend money too, to buy their software.  Enough with my grumbling, I know you’re tired reading this post and you want the answer.  The solution is to install yahoo messenger version 8.

1. Google or search the installer or download here (please check if the file had a virus)

2. Install the software

You will be annoyed when this malware changed your “Open” command in the right click menu to “b-b2g” and “Explore” command to “Owned” when you right click a drive or folder.

• [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\explore]
  • (Default) = “Owned!”
