More on Windows System State Analyzer

I today had the chance (staying inside to stay out of trouble on this day :-) to play a bit with Windows System State Analyzer, which is currently in beta (as per the application title). I installed it on Longhorn/Windows Server 2008 beta (build 6001, beta 3). Installation went fine, and the application is a .NET application.

However, the application fails to take a snapshot on the beta. I can start the application and begin taking the snapshot, but after several minutes (yes, it takes quite a while), I get an error saying this:

---------------------------
Windows®  System State Analyzer (Beta)
---------------------------
Error taking snapshot.
---------------------------
OK

I have to check whether the application would work, say, on Windows XP.
