I found a way to get this working for me. I have the standard version of the game (not Steam version) I had to add the game to Steam as non-Steam game, run steam VR, start the game up which loads the launcher, logged in and VorpX hooked it this way. Every other way it would not hook the game. Hope this helps.
I’m trying your meathod but can’t get it to work.
Do you have the launcher excluded? and which profile and exe are you using
Open vorpx before or after you open the launcher ?
