I get that message when launching SteamVR. No idea why I am getting this. Anyone know a fix?

I had this problem from one day to another. What helped me was to shutdown steam and steamVR, find the file "C:\Users\<Username>\AppData\Local\openvr\openvrpaths.vrpath" and delete it. Then start steam -> steamVR again.

I noticed that this file does not change when you do a fresh install of steam, so just reinstalling steam and steamVR will not solve the problem.

I was having a slightly different issue same message but with (300) and I couldn't find much online about it.
Turns out the razer hyder drivers for steam VR which were mentioned in that vrpath file were causing the issue. I just removed the file as you suggested and it started working again.
Thanks :D

A friend has a problem with Vr so it says: Steam Vr couldn't started. We deleted the file and restarted steam and it works! Thank you very much:)!

ive had this problem and spent many hours looking
what did it for me was download a program called driver uninstall utility and completely removing all graphics card drivers then re installing an older version. i used nvidia driver 381.89

It seems that when you move SteamVR or change anything in the SteamVR, SteamVR can not find the specific files and refuse to run, producing the error.
My solution was to delete SteamVR (and SteamVR under "Tools"). Reinstall both. He will create all files he needs and it should work again. :)
