I got an email back advising me to install a previous version 1.2.2 as opposed to the current one that is 3 or 4 generations later. I haven’t used their download link, but I did uninstall the AR version then install the workout version. It works now. No explanation why it dint run the AR version, my laptop exceeds the required spec /which is quite high - i5, 8gb ram, 2gb graphics card). The only thing I can see different is that although I have 4gb graphics memory, it’s an R5 generation Radeon, and they spec R9 generation.
Aaaanyway, I’ll give it a spin this afternoon, but I actually really liked the BigRingVR interface. I’ll also try FulGaz.
