I have had this problem for the past 8 months, and I have been unable to play LSPDFR for those past 8 months due to this problem. I will detail the problem below:

 

-When I launch GTAV using RAGE, the game will take a while to load, prompting the RAGE launcher to say "This is taking longer then usual"

-Once the game loads, it is the vanilla game with RAGE not being hooked.

-Upon Alt-tabbing from the game, the error message displayed is "GTAV Launcher failed to start"

 

The following attempts at solving this problem are below:

- Completely reinstalling GTA V multiple times (including a fresh LSPDFR install every-time)

- Double and triple checking I have the latest RAGE installed.

-Ensuring my OpenIV has updated the update.rpf

-Running RAGE as an administrator

- Locating ClientRegistry.blob and renaming the file to ClientRegistryOld.blob

- Adjusting launch settings in RAGE (Direct X version, windowed mode)

-Re-launching RAGE during game startup

 

I am practically begging for help at this point. I see multiple posts on this forum regarding the same issue with no replies. I have made a thread in the past in July 2017 with the same, issue, and to no avail.

 

There must be a solution to this problem somewhere.
