NT4 is not supported by .NET 2.0 - see http://www.microsoft.com/downloads/d...DisplayLang=en for the list "Windows 2000; Windows 98; Windows 98 Second Edition; Windows ME; Windows Server 2003; Windows XP".
I think this is largely because of a MSI 3.0 requirement on NT based systems; MSI 3.0 supports "Windows 2000 Service Pack 3; Windows 2000 Service Pack 4; Windows Server 2003; Windows XP; Windows XP Service Pack 1" (http://www.microsoft.com/downloads/d...isplayLang=en), so at least the Best Fit option is doing the right thing on NT4Sp6.
With this information in mind, does the current behavior make sense, or what behavior would you like to see?
