Okay, for anyone who is running either windows 95, 98, 98SE or ME, it is possible that you get a message up about ‘downloading form the official site’ when you try to download the BETA version of MSN 6. To fix this, go to
http://download.microsoft.com/download/WindowsInstaller/Install/2.0/W9XMe/EN-US/InstMsiA.exe and let it download. It will prompt you to restart. Do so, then redownload MSN 6 and the problem should be gone. 🙂
