They have a test program you can download and see if 3D will work on your computer. That worked without issue, but it does not install within PD, just a test of your video card. So I imagine a conflict between PD and Pixelan.
Pixelan support is taking a look. Sent them my video card information. They have offered a refund if it can't be resolved!
Running Windows 8.1
Anyone else having issues with Pixelan software installs or is it just me?
