Tortoise SVN freezes when trying to lock/add/commit changes of SolidWorks files

Tortoise SVN sometimes freezes when SolidWorks files get changed when the user tries to lock/add/commit files.  This is caused by the sldShellExtServer.exe process conflicting with Tortoise.  Disabling the shell extensions that SolidWorks installs on the computer removes the conflict so that SVN can work properly.

The Fix

The fix involves disabling the shell extensions, so disabling them is not recommended if the user makes use of these features.

  1. Download ShellExView from http://www.nirsoft.net/utils/shexview.html
  2. Disable the following items:
    • SLDASMIcons Class
    • SLDDEWIcons Class
    • SLDPRTIcons Class
    • SldShellExtension Class
    • Solidworks Document Thumbnail Handler
    • SolidWorks file Info Tips Class
    • SolidWorks file Preview Class

Once these items are disabled, SVN should work properly.

    1. Not really sure. I don’t really know if they’ve fixed it in the latest version of SolidWorks. I am still using the 2011 version.

  1. Great, this issue was VERY annoying.
    Im just not sure what features I actually disabled but sldwrks seems to work as before !

  2. Thanks for this – after hours of trying to figure out what the hell was going on I followed a suspicion that Solidworks was involved, leading me here.

    Out of curiosity, how did you identify the shell extensions as the problem? Did you use any specific diagnostic tools? I’m not the best at troubleshooting crashes, so I’m trying to learn.

    1. I’m glad this helped you. There wasn’t any procedure that I followed really. I just ended up Googling around and found clues to a solution – the same way you did. I would say your approach is right!
