Version 7.03 works fine in Server 2008 (tested, I'm a registered owner of TC software) !
With just one exception it is fully fucntional:
It doesn't see the System32 system folder (redirects to the SysWOW64 folder).
This is not Server 2008 specific, TC know about the problem: http://www.ghisler.ch/board/viewtopic.php?t=7077
