Vray Vision Standalone Export Model - System Requirements?

Ive built a landscape model and have created a standalone export model in vray vision which I am hoping to give to my clients as part of the final plan package.
Model works great on my PC but Ive tried to run the model on one of our admin staffs pc (ex-lease shitter) and its getting stuck in initializing stage,

Does Anyone know what PC specs are required to run it? I’ve looked all over the chaos website but no luck
