OpenVR: failed to find interface ''IVRCompositor_027"

Question

I cloned the openVR repo and went directly to compile the driver_sample and hellovr_dx12 and hellovr_opengl projects. The builds were successful. But both the helloVR applications failed to launch with an error:

Failed to find interface 'IVRCompositor_027'

I have no clue except My guess is that the variable IVRCompositor_Version might need to be set appropriately, but how to find the right version?

Using SteamVR 1.15.15 on Windows 10, VS2019. The HMD (HTC Vive) is correctly setup.

Answer 1

I updated SteamVR to the lastest version and the issue is solved.
