"Microsoft .NET Framework 1.1 is required for installation. Setup cancelled." I need to install Exchange Best Practises Analyzer. 3.5 SP1 is installed. Do i install .NET 4? Also need to work this out as my other question in ExpertExchange is related to this. Isn't 3.5 backwards compatible for 1.1??

1.1 is unique and 2.0 onwards are all "Compatable". if anything needs 1.1 then you MUST have 1.1 installed no matter what else you have.

OK 1.1 installed now but i still have the problem with the Exchange 2007 SP1 install being blanked out, in the past has that been related to .NET? In my experience it has been .Net, it wouldn't be Java or something would it?

What do you mean by "Blanked out" Do you get errors reported?

Has any one had time to observe the jpeg above to see if they've seen anything like this before with .Net?
