I'm trying to get ServiceDesk working on SQL 2008 SP1 at the moment (for a dev environment only) and I'm getting stuck on the SQL Server 2005 Management Objects Collection being not installed, I've installed the SQL 2008 Management Objects but it appears the installer is checking for the 2005 version only.
Read somewhere on kb.altiris.com that SQL 2008 'may work but is not supported' but can't find the link right now.
would be interested to hear if anyone is able to get it running..
