Description
A tiny utility for easy switching between Rockstar Games Launcher, Steam, Epic Games Launcher with just only one game installation.
You don't have to install this pretty big game for each launcher and consume so much disk space by duplicating game files.
You can just manage all launcher editions by using one game installation and just switching platform-specific files. It saves so much time you'd spend by downloading and fighting stupid issues.

Guide
It's complain to give a text here, just watch entirely one of these tutorials if you have game installed from:
Steam - https://youtu.be/12D6Dzm94Ns
Rockstar Games Launcher - https://youtu.be/be6NTGniXjM
Epic Games Launcher - https://youtu.be/eU_xPIpNRgw

Requirements
- 64-bit Windows 10 (Windows 7 wasn't tested)
- .NET Framework 4.8

FAQ
Q. Why are these tutorials so difficult?
A. There is needed to force all platforms using same game folder and making Rockstar Games Launcher determine all of them as installed. I recommend you to watch the tutorial entirely without any actions, and start doing all at second watch, or if you’re not so fast, set speed to 0,75x or 0,5x.
Note: «Move» in tutorials is NOT copy+paste (Ctrl+C, then Ctrl+V), it’s cut+paste (Ctrl+X, then Ctrl+V)

Q. How to determine what’s my current version of Switcher and files?
A. Switcher version can be seen in Help — About at bottom left, files versions are shown in main window
