Is there an easy way to roll back from ST9 MP4 to MP3.
I recently upgraded to MP4 and then I started crashing frequently.
The most common action causing the crash is changing the gage of a sheet metal part.
What is the path of least resistance to roll back to MP3?
Use the "Programs and Features" command and select the entry in the upper left to Show Installed Updates. Find Solid Edge ST9 in the list and double click to uninstall. It will roll back to the last installed update.
