Hi Casey,
To follow up with my previous answer, I had some help from Epic Games. Can you please check the plugin version number found in the “About” under the Twinmotion 2020 menu inside Archicad? We would like to make sure the right version is being installed first.
Also, something else important to know, that Twinmotion needs to be opened at least once before trying to do a synchronization.
Now for the computer specs, we doubt this would be the issue and if that was the case, we would think that Twinmotion should at least start. We think it has to be something else.
So if we could get the Plugin version number from you, that would be a good place to start!
Looking forward to hearing from you soon!
Best regards,
Minh
