Well, waited until SP1 before upgrading.
Mistake? could say that, random crashes etc in the middle of doing something/anything got very annoying.
VAR recommended and gave a registry hack to do with PDM and said that they would be in SP2.
Well, that came out so in for a penny as they say.... installation crashed with couldn't register file. Cancelled it and two other error boxes.
Well at least SolidWORKS loads .... aye without PDM! Its thrashed that.
getting more like MicroSHITE every upgrade.
