Hi ALL,
I recently had a new PC with Vista and Inventor pro 2009 which includes AutoCAD Mech 2009.
The reason that I post this thread here is that I think this is a general update problem for AutoCAD 2009 version.
My problem was that I could not open any programs on Vista platform after updateing AutoCAD 2009. I also found the Vista's sidebar doesn't work at all.
I then switched to an earier system restore point (which was at the time before downloading Autodesk updates) and everything were back to normal.
I also noticed that the problem most likely caused by the Microsoft SQL sever updates which is a part of AutoCAD 2009 updates.
I now fomatted the hard driver and reinstalled everything but without any AutoCAD & Inventor updates.
All programs run fine.
NOTE:
1) It runs fine when my new PC not networked. The problem only happens when it networked.
2) It was fine on my old PC with Windows XP pro.
I STRONGLY SUGGEST YOU DO NOT INSTALL ANY AUTODESK UPDATES FOR 2009 VERSIONS UNTILL THIS PROBELM IS IDENTIFIED BY AUTODESK.
PLEASE ALSO LET ME KWON IF YOU HAVE A BETTER SOLUTION.
Cheers
