I get this error ALMOST every time I create a folder in the FeatureManager tree (not every time, I think it happens more often for more complex parts)
After this error appears the first time, it then appears whenever I try to perform and action (create/edit a feature or sketch, save, etc). It's not a crash, but since it forces me to restart SW, it might as well be.
Anyone else have this problem?
SW 2011 SP1.0
Figured this one out! Was having the exact issue in SW2014, it seems to be caused by a corrupt temp file. You don't need to create a new user account, just close solidworks, browse to your temp folder and clear everything, then restart solidworks. Temp file is located here in windows 7:
C:\Users\<your username here>\AppData\Local\Temp
for example mine was C:\Users\ALEX\AppData\Local\Temp\
