According to the informations provided by the Windows 7 Compatibility Center at the following web address
http://www.microsoft.com/windows/compatibility/windows-7/en-us/Search.aspx?l=en-us&type=Software&s=Visual%20Studio%20.NET
Visual Studio .NET 2002 should not be compatible with Windows 7, because it is not listed in the query results: if you really need to run Visual Studio .NET 2002, you must try running it in compatibility mode or rely on virtualization by using Windows
Virtual PC with XP mode (http://www.microsoft.com/windows/virtual-pc/) or a virtualization program.
Otherwise, you must install at least Visual Studio 2005.
Anyway, the rule is always the same: the most recent version of a program must be the last to install.
Bye.
