OVR Platform Util Weird Error

Hi guys,


When i run "[...]\Assets\Oculus\VR\Editor\Tools>ovr-platform-util help", i get the following error:

I google it but i seem to be the first one with this error ;(


Level 2

The problem was that my CD Drive had the letter 😧

After changing 😧 to Z: via DiskManagement Tool, it worked again 🙂

For me, this had to do with the fact that my D drive was still locked with BitLocker. Error: UNKNOWN: unknown error, open shows which file/drive it cannot access

Level 2

Nothing I try seems to fix this.  I've never even had a D Drive, or any kind of CD Drive on this PC.


I'm getting this same error now, and it's not due to a wrong drive. It doesn't even matter if I include the arguments, I still get this exact same error. And I can't get Oculus Developer Hub to upload a build, either, as it just gives the vague "Build Upload Error - an error has occurred" that's all the rage these days.

Level 2

Same error and also can't upload via Oculus Developer Hub due to the error "Build Upload Error - an error has occurred"

One point of data: my coworker has 2.7.1 and it works fine for him. I'm pretty sure I HAD 2.7.1 when it first broke for me today, then I updated to 2.7.2 and it still didn't work. So it doesn't seem to be a specific version so much as something machine-specific.

Level 2

Was able to fix mine, apparently having my headset's Link cable plugged in was causing the issue...creating a sort of hidden D Drive even though it was powered off...
