Thanks for replay.
Yes I have but after some time I face same error.
But did RX come up with any issues?
Do you get these crashes when you do the same tasks/work flow. If so it could be that there is a bug in the software and it may be worth contacting your VAR. If you feel the crashes are random creating an Rx which Dave suggested could help determine what is causing the crash as it could be an issue with the SOLIDWORKS install, or part of the software, etc. Although it looks like you have the Rx tool open under the crash so you could try creating and looking at the log files which it creates and look for key words relating to 'Crash', 'error' etc.
Without additional information it would be very hard to determine why the software is crashing and a fix, without just saying to repair the install or re-install and hope that works.
If you could provide more info (or contact your VAR) hopefully someone will be able to get to the bottom of the crashes.
In RX no any issue..
