This error occurs when trying to run a 32-bit-only macOS app on macOS Catalina (version 10.15) or newer due to the removal of support for 32-bit-only apps. Some affected games have a patch or other workaround to resolve this; refer to the individual game pages for details.

Install Media Feature Pack (N/KN editions of Windows)
N and KN editions of Windows will have issues starting games that require the Media Feature Pack.
- Windows 11: Go to Start, then select Settings > Apps > Optional features. Select View features, then select and install the Media Feature Pack.

Bypass OpenSSL SHA bug on Intel 10th gen and later CPUs
- OpenSSL 1.0.2 beta (Jun 2014) to OpenSSL 1.0.2k (Jan 2017) contain bugs that either cause a crash or bad SHA (Secure Hash Algorithm) values on processors with the SHA extensions, such as Intel 10th generation and later. Unreal Engine version 4.13 (Sept 2016) to version 4.21 (Dec 2018) contains the old version of OpenSSL, so any game built using those versions is possibly affected.
|Disable SHA extensions in the OpenSSL library|
Check error logs
Many games will generate a log file in the installation folder or configuration file location containing details of the error that occurred.
Override localization (Linux)
- Some Linux games expect localized file names in ways that fail on certain languages (e.g. Turkish). This may prevent the game launching or cause other issues. Launching the game from the terminal with the
LC_ALL=Cprefix may work.
Dependencies install at every launch (Steam)
|Delete install VDF and redist folder|
Game switches to windowed mode or minimises when launched
This is usually caused by another program stealing focus, e.g. antivirus (some antivirus programs have a "game mode" that can be used to prevent this). Identify the program, then adjust its settings or disable it. Samsung Magician is known to cause this behaviour.
Games may also switch to windowed mode if an unavailable resolution has been chosen in the game or specified in a configuration file.
