Hi all,

The story is, my company have 1 2009 standard using and wanna buy 1 more seat of the Solidworks. As we prefer to have the PDM function, then we choose the 2011 professional.

PC-A using Vista-64 with SW2009 Std SP5.1.   Run with no problem.

New PC-B using WIN7-64 with new install SW2011 Pro SP4.0.   Run Smoothly.

But after we update the PC-A's SW to 2011 Pro SP4.0.

-the Solidworks explorer ---Crash on start

-The Tool Box Config  ---Crash on start [Program icon/  task plane/ menu item]

-on any drawings, once use smart dimension, click confirm[the tick] ---Crash immediately.

....

Hope I can get some hint to fix it.

Best Regards to all,

Ivan
