If the problem persists please try to register the Installer service:

  1. Open the Command Prompt (Start > Run, type CMD)
  2. Type in the following command: msiexec.exe /unregister
  3. Press enter, this will unregister the service.
  4. Now re-register the service using the following command: msiexec /regserver
  5. Retest the SOLIDWORKS installation
