Editor’s View: The “Custom Engine” Quirk
“Mewgenics isn’t built on Unity or Unreal; it runs on a Custom C++ Engine written by Tyler Glaiel. While this makes the game incredibly optimized for handling hundreds of cats, it also makes it picky about your Windows environment.
In my experience with previous McMillen Glaiel games like The End Is Nigh, startup crashes are almost always caused by missing C++ libraries or Refresh Rate conflicts. Before you panic and refund, try Method 2. It fixes 90% of launch issues for this specific engine.”
You have waited over a decade for Mewgenics. You pre-loaded the files, cleared your schedule, and are ready to breed the ultimate cat. You click “Play,” and… nothing. Or worse, a cryptic “Fatal Error” pops up.
Launch day issues are frustrating, especially for highly anticipated indie titles. Whether you are facing a black screen, random Crashes to Desktop (CTD), or missing DLL files preventing the game from starting, this guide covers the most effective solutions to get you into the simulation.

Check First: Mewgenics System Requirements
Before debugging, ensure your PC can handle the simulation load. While the graphics are simple, the genetic calculations require a decent CPU.

Method 1: Verify Game Files (Steam)
Corrupted installation files are the #1 cause of immediate crashes. If your internet fluctuated during the download, a critical data chunk might be missing.
For Steam Users:
- Cliquer avec le bouton droit de la souris Mewgenics in your Library.
- Sélectionner Propriétés > Fichiers installés.
- Click “Verify integrity of game files”.
- Wait for the process to finish. Steam will re-download any corrupted sprites or logic files.
Method 2: Update Drivers & Visual C++ Redistributables
Since Mewgenics is a native C++ application, it strictly requires the Microsoft Visual C++ libraries to run. If you just reinstalled Windows, you likely don’t have them.
- Visual C++ All-in-One: If you get errors like
MSVCP140.dll missingouVCRUNTIME140.dll not found, download and install the Microsoft Visual C++ Redistributable 2015-2022. Install both x86 and x64 versions. - GPU Drivers: Even for 2D games, outdated drivers can cause OpenGL and DirectX conflicts. Update your NVIDIA or AMD drivers to the latest version.
Method 3: Fix Black Screen & Refresh Rate Issues
If you hear audio (cats meowing) but see a black screen, the game might be trying to launch in a resolution or refresh rate your monitor doesn’t support.
Force Windowed Mode:
- Cliquer avec le bouton droit de la souris Mewgenics in Steam > Properties.
- In Launch Options, type:
-windowed - Launch the game. If it opens, you can adjust the resolution in the in-game settings.
Disable Fullscreen Optimizations: Right-click the Mewgenics.exe file -> Go to Compatibility -> Check “Disable fullscreen optimizations”.
Method 4: Common Error Codes & Fixes
Here are specific solutions for the most common error messages:
Error 0xc0000005 (Access Violation)
Usually caused by strict antivirus software blocking the custom engine. Whitelist the Mewgenics installation folder in Windows Defender or run the game as Administrator.
“Missing MSVCP140.dll” / “VCRUNTIME140.dll”
This confirms you skipped Method 2. Reinstall the C++ Redistributables immediately.
“Fatal Error: Failed to load save”
Your save file might be corrupted. Navigate to Documents\My Games\Mewgenics\ and try renaming persistentgamedata1.dat à persistentgamedata1.old to force the game to create a fresh save.
Method 5: Fix Low FPS & Simulation Lag
Is the game running like a slideshow when you have too many cats?
- High Priority Mode: Open Task Manager > Details > Right-click
Mewgenics.exe> Set Priority > High. - Laptop Power: Ensure you are plugged in. The simulation logic throttles heavily on battery power.
- Reduce Particle Effects: In the game’s options menu, verify if there is a “Low Quality” mode for particles/weather effects.

FAQ
Q: Does Mewgenics run on Windows 7?
A: Officially, no. The custom engine uses modern APIs that require Windows 10 (64-bit) or newer.
Q: Will reinstalling fix the “Fatal Error”?
A: Reinstalling often doesn’t fix registry or C++ library issues. Try Method 2 (Visual C++) first, as that is the most common culprit for this engine.
Q: Is the game compatible with Ultrawide monitors?
A: Custom engines often have black bars on Ultrawide. Check the XMODhub community mods for potential widescreen patches.
