If you're installing the .NET Framework 2.0 Beta 2 on an NT-based machine (NT, Win2K, XP, Windows Server 2003) then you'll need to have MSI 3.0 installed.
If you're installing the .NET Framework 2.0 Beta 2 on an 9x-based machine (98, 98SE, ME) then you'll need to have MSI 2.0 installed. This is necessary since MSI 3.0 only supports NT-based platforms.
You can figure out which one is installed by looking at the major number from [HKEY_CLASSES_ROOT\CLSID\{000C101D-0000-0000-C000-000000000046}\DllVersion].
