If Protontricks Doesn’t Work
Some games need a special Microsoft file (called the C++ Runtime) to work properly.
Normally, we’d use Protontricks to install this — but sometimes Protontricks doesn’t do the job.
Here’s how you can install it manually. Don’t worry, it’s easy!
Manual Install Steps
-
Go to the official download page:
Microsoft C++ Redistributable Downloads -
Download this file:
X64 Redistributable for Visual Studio 2015-2022
(The file name will be something likeVC_redist.x64.exe
) - Move the downloaded file into your game’s folder:
- Epic Games (e.g., The Callisto Protocol): ~/Games/epic/TheCallistoProtocol
- GOG Games: ~/Games/gog/your-game-folder
-
Open Junk Store and go to the game’s page.
-
Open the sliders menu (press the button with the sliders icon).
-
Choose Run EXE in game folder.
-
Select VC_redist.x64.exe
- Follow the install instructions like you would on a Windows PC.
That’s it! Once it’s done, try launching the game again — it should now work properly.
Extra Tips If the Game Still Isn’t Working
-
Check ProtonDB.com
Other players often share which Proton version works best or if extra steps are needed. -
Try a different Proton version
The default “Experimental” version can be buggy. Try using GE-Proton — it’s more stable in many cases. -
Game works with “Run EXE” but not the Play button?
Try resetting the launch options in Junk Store to default. -
Still no luck? Try a fresh start.
You can delete the game’s prefix (basically its “Windows install environment”) from Junk Store.Be careful — this will delete all saved data and settings for that game!
