Anyone that reads any of these forums can see that S3D has never really had a handle on their Linux version for some reason. Even way back it was always some hoop you had to jump through here and there to get it to run but it was still sold as commercial software with Linux support.
And today its the same.
I wont name the issues here but look around and they are easy to find. It works great unless you are crazy enough to think that you shouldn't run software like this as root. But about 36 hours ago I put in a support request for my paid copy of S3D no longer running as it could not 'activate' and I needed to run it for an urgent project.
Crickets from S3D.
I worked out the issue and its hilarious. So if anyone running Linux wants to know the 'fix' hit me up.
