Hi,  
I’m trying to install Slicer on a Windows EC2. I’ve tried manually installing the NVIDIA drivers on a GPU instance and have also tried using an EC2 AMI with prebuilt NVIDIA drivers, but neither work. I get a message about insufficient graphics availability. The EC2 instance has 1 GPU with 24 GB memory and 4 CPUs. The driver is a Tesla A-Series A10.

I suspect this is because the drivers don’t support OpenGL 3.2 (they support 4.6).

Has anyone any idea how I can fix, or investigate the error further?

I’ve attached a screenshot of the error and a screenshot of the driver (I’ve since disabled the Microsfot Basic Display Adaptor, but this doesn’t fix it)

The issue is just Windows Remote Desktop Protocol (RDP) downgrading OpenGL API version. Updating the RDP server and/or client should fix this, but if it is not feasible then you may consider switching to a remote control software (e.g., VNC).
