    Right click on it and select Run as Administrator 

  3. In the command line, enter the file path of RTXpropertiesCheck.exe to run it.

  4. If you can't run the RTXpropertiesCheck.exe, and receive the error message :



    Run the vcredist_x642013 file included in the archive.
    And try again

  5. If the result is RTX64 properties valid, Pyramix should now be able to start in MassCore mode.

If the problem persist, please take a screenshot of the RTXpropertiesCheck.exe command prompt and contact support@feedback.merging.com
