System Center Operations Manager Installing with a DB on SQL2008 R2

I've wasted a whole day of trying to get the dbcreate tool to run on Windows 2008 R2 with SQL 2008 R2, all posts on the net seem to end without a solution, there are a number of KB articles, about copying DLL's etc, all end up with either a namespace error or just no errors in the log file at all.. I found one simple solution to this, dont use the install with SP1 present, just use the DBCreateWizard on the Non SP1 install and it runs fine! - or so far so good. This will probably bite me in the arse shortly, but for now I have a DB created which is a step in the right direction.
