I've installed Messenger 7.5, Repaired it, Uninstalled it and then Re-installed it, but for some reason Messenger Plus! keeps saying I need to have Messenger 4.6 or later installed in order to install Plus!
If you installed Windows Messenger 5.x (newer version, not the one that came with WinXP), uninstall it. Make sure Windows is up to date (servicepacks etc.) then redownload and install the latest MSN Messenger, available at http://messenger.msn.com/
Can't install Plus!
