Crash on startup on specific host


I am not sure this is purely related to VR but I have a client which cannot run a VR app we built for him.
The platform is a highend laptop with GTX980 (desktop model) running w10-64 home.

I was wondering if there was any way to customize the build to make more portable like a failsafe mode even if the perfs would slow downa bit ?
Is there any need to try building without limited API support (only DX10 or DX11 for instance) ?
Thanks a lot for your help
