SolidWorks crashes everytime I make a sphere and hit the "save" or "save as" button.

Have you restarted your computer/Solidworks? that would be the first place to start. Then try the following

  1. Step 1:

    The registry file often gets corrupted and may need to be reset. Close Solidworks. Go to run and type in regedit (if you're windows 7 or vista open up the start menu and search regedit). Once you have regedit open, open up the hkey_current_user folder, open up the software folder and rename the SolidWorks folder to something like SolidWorksOld. Then open SolidWorks back up and try to recreate the issue.

  2. Step 2:

    If that doesn't work, you want to try to repair the installation from within the programs and features, and then try to recreate the issue.

  3. Step 3:

    If neither of those options work, uninstall and reinstall Solidworks.
