Fix game crashes and missing DLL errors when 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.

Download the C++ Redistributable
Go to the official Microsoft download page: Microsoft C++ Redistributable Downloads

Download the file: X64 Redistributable for Visual Studio 2015-2022 (the file name will be something like VC_redist.x64.exe)
Move the File to Your Game Folder
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 the Game in Junk Store
Open Junk Store and navigate to the game's page.
Open the Sliders Menu
Press the button with the sliders icon to open the menu.
Run the Installer
Choose Run EXE in game folder and select VC_redist.x64.exe.
Complete the Installation
Follow the install instructions like you would on a Windows PC. 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 — Try using GE-Proton as it often has required fixes for non-Steam games.
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!
