We’ve resolved some past issues of some users not being able to use Dimension, however there is a known issue still remaining.
Video cards that do not support a specific instruction set (AVX/AVX2) will not be able to run Dimension. This is primarily video cards from early 2012 or earlier.
At this time our System Requirements checker is unable to ‘catch’ this and leads to the application crashing on the Start Screen when the New Document or Get Started buttons are clicked.
At this time we are unable to fix this issue or catch to throw an error. We are continuing investigation on this.Diego Carneiro commented
My current video card is GeForce Nvidia GTX 1060. That Graphic Card supports the AVX/avx2.
