How To Reset SOLIDWORKS Registry

How to reset the SOLIDWORKS registry (and then revert if needed).


The Windows registry keys associated to SOLIDWORKS installation and settings can be reset to default to start SOLIDWORKS as a default installation or as a troubleshooting step to resolve unexpected behavior. The reset registry can also be reverted, if needed. 


CAUTION: Incorrectly editing the registry can severely damage your operating system. The SOLIDWORKS Technical Support team strongly suggests that you back up the registry data before making any changes to the registry. If you are unfamiliar with the registry, please work with your IT group to make these changes.
