I have installed DevExpress components and Report Builder and on testing I had no problem.
After installing SDAC 4.0.0.6 I get an error on closing down Delphi which wasn't there before installing SDAC. Following text appears:
CodeGear RAD Studio for Windows has stopped working.
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
I had the same problem on the previous Vista installation I replaced with the new one - after installing SDAC. So I guess it's something to do with that. Disabling the Dataset Manager makes no difference either

Anybody got any idea on this? Uninstalling SDAC removes the problem so I'm sorry guys - it has to be something to do with SDAC and Vista.
