How to fix SERVER ERROR (Code: -10)

This is happening because the SteamVR driver associated with KinectToVR is disabled, blocked and/or unlisted from the drivers list.

For ALVR users:

If you're using ALVR it will disable other registered external SteamVR drivers by default.

You can go to this page to see how to fix it.


Make sure the driver isn't disabled or blocked in SteamVR.

After restarting SteamVR, KinectToVR should show "Sucess!" in the Kinect Status label.

If the driver wasn't in the add-ons list.

This means the driver is missing from openvrpaths.vrpath, the file that SteamVR reads to find various important directories, including external drivers.

You can use this tool to register the driver automatically.
Please make sure that both SteamVR and KinectToVR are running before opening this.

Register-Driver.exe


It might throw a warning saying "Windows protected your PC". The app is safe. Here's a VirusTotal scan and the source code.
Click on More Info, then Run Anyway.

I'm still having issues.

If the driver is enabled and you restarted SteamVR after enabling it, and you're still getting the server error. Try checking if you have third-party firewall software that could be causing KinectToVR to be unable to connect to the driver.

If you have no such software. You should come ask us for help on Discord.
