Mocha AE - no QT platform plugin could be initialized

Help, I cannot start Mocha Ae all of a sudden, and every time I try, I get this message. Immediately after hitting OK, Ae crashes. 

Error message:

I have reinstalled, after effects and removed plugins. I did the same for premiere pro for good measure. I tried switching to open cl from cuda, I tried not using hardware at all. I tried installing a trial of MochaPro and that works. I did run in command prompt: sf/scan now. That didn't resolve the issue. I have no way of only reinstalling MochaAE as it is bundled with Ae. I cannot even open Mocha Ae to clear the cache, I cannot find instructions as to where the cache is online to manually clear it.

    Hi, I have tried reinstalling.
    I just tried using the cleaner tool, and removed everything, restarted, and tried to use mocha ae, only for the qt platform failure message to pop up again. Not sure what to do here.

     


    program files > adobe > and there was a folder "Common" > change the name of the folder to "Common.old"

    Then restart adobe after effects > Run as administrator > It should work

      Sorry for the delayed response.

      Have you tried reinstalling After Effects? If it didn't help, try uninstalling it using the Adobe Cleaner tool and reinstalling. The cleaner tool ensures the removal of all the residue files.

      Let us know how it goes.


      Thanks,
      Nishu
