What causes the “Invalid Game Executable” message in Apex Legends?

R5Apex.exe quarantined: One of the most common cases causing this problem is a false positive or legitimate threat affecting r5apex.exe. It turns out that this problem is quite common with AVG, Avast, and other security packages. If this scenario applies, you can solve the problem by restoring the executable from the Virus Vault.

Game file corruption: This error may be caused by some type of underlying corruption that affects the game files. In this case, you can solve the problem by using Original Scan and Repair to find and repair any inconsistencies in the files related to Apex Legends.

Runtime incompatibility: It turns out that the Easy Anti Cheat engine used in Apex Legends is causing some incompatibility issues with Windows 10. In this case, the problem can be resolved by running r5apex.exe in Windows 7 compatibility mode.

Damaged Easy Cheat Engine: Another case that can cause this error is a damaged Easy Cheat Engine that is not working properly. This causes the game to shut down to prevent cheat attempts. In this case, you can fix the problem by going into the EasyAntiCheat folder and running the restore procedure from the installation executable.

Missing Windows 8.1 updates: In Windows 8.1, most often this error occurs when your version of Windows is missing two stack updates that your game needs to run smoothly (KB3173424 and KB3172614). In this case, you can fix the problem by manually installing the two updates and restarting your computer.

Corrupted game cache: If you get this error when starting a game, the cache file is probably corrupt, causing the game to crash every time you try to run it. If this is the case, you can solve the problem by clearing the cache to get the game to start without returning to the previously created data.
