Hey, I've come here for support after trying nearly everything else:

As the title explains I'm having some trouble for rage hook and can't seem to hook my game session. I can load GTA just fine, but when I get into the game and to the main menu screen I'll tab out (to make sure rage has loaded) and find that it hasn't, giving the following error message: "GTAVLauncher.exe failed to start. Please try again. If the problem persists, please restart your computer." (I've attached a screenshot of it). I have restarted my computer multiple times, but to no avail. I have reinstalled GTA, LSPDFR and Rage hook (In that order) along with reinstalling rage hook multiple times. I can't seem to figure out what the issue is, as I have played LSPDFR on this PC before (I recently deleted it in favour for a fresh install). I have tried everything I can think of, including running it in admin mode and am at the end of my tether. Someone on reddit suggested running raga hook after GTA had loaded, but that didn't seem to work. At this point and advice would be greatly appreciated, as I thoroughly enjoy playing LSPDFR and would be disappointed if I couldn't play it anymore. (To say the least)

 

I eagerly await any responses and thank you in advance for said responses.

Make sure no GTA.exe files are running as admin.

How would I do that? Just not select anything to run as admin?

Try launching the game thorugh the steam app and then try to load rage when gta 5 is done loading. I had that same error and this method seemed to fix it.
