So, you need to have windows 10 pro in order for this to work. If you don't, then you will need to set up Virtual box and I don't really know much how to use it. If you do have windows 10 pro, do as follows.

1) go into programs and features

2) select built-in windows features - or something like that

3) there is a list of apps, like internet Explorer, ftp clients, etc. You want to scroll down and select Windows sandbox.

4) Google on the internet how to make windows sandbox shared folder, I'm on my phone so can't really provide the way to do it. But it's pretty easy, you just create a config file and open the sandbox just by opening the config file.

5) when you are in the virtual machine, install EGS and make a fake account. Activate the game and select Installation folder the one that has been created on your desktop (the shared one. We need to select this one as everything in this virtual machine gets wiped once you close the window, this way you keep the installed game files)

6) once download is finished, run the game. It will ask for social club login. Just do it and it should activate GTA on your social club account

7) close the virtual machine destroying all the traces of EGS

8) you are only left with the GTA game files and activated social club account. You can move those files to your desired location. Probably in the social club folder in program files.

9) run the game via social club, no egs needed!
