    I receive the following error: “Unable to connect to Steam VR. Error: Init_HmdNotFoundPresenceFailed” when trying to run the program. I believe it is because my Steam is not installed in the default folder, but I don’t see any way to change that in driver4vr. Ideas?

    does SteamVR start with no issues ?

    Same here, to me everything starts fine, both steamvr and driver4vr, but then they both immediately give the error Init_HmdNotFoundPresenceFailed. I googled and bit and found an old github (2017) thread where they said that a possible solution would be to set “hmd_presence” in the driver.vrdrivermanifest to “*” (instead of the value []), I tried that and now it gives the error Init_HmdNotFound followed by a steam vr fatal error

    hi. does the problem still exist?


    Hello, I have updated driver4vr since I did not occupy it for a while and now the same problem happens to me, the program worked perfectly before (6 months approx.), I do not know if it may be because I occupy windows 7. Even so I would like to know if there is a solution since I cannot update the operating system for various reasons.
