That issue is widely reported for games with Easy Anti-Cheat, such as Halo: The Master Chief Collection. When some players try to launch the game, a Launch Error Invalid game executable error message pops up.

How can I fix the Invalid game executable error for Halo: MCC?

1. Run the game with administrator privileges

Note: Players who play Halo: Master Chief via Steam should also run Steam as an administrator. Check out our guide to running Steam as an administrator for further details.

2. Disable Easy Anti Cheat

Open the Master Chief Collection page in your Steam or Xbox app game library and select Play. A small window pop-up will then open that includes two options. Select the Play Halo: MCC Anti-Cheat disabled option in Steam or Halo: MMC Anti-Cheat Disabled setting in the Xbox app. Note: You might not be able to play Halo: MMC online with Easy Anti-Cheat disabled. However, Halo might at least start for you to play it single player with Easy Anti-Cheat disabled.

3. Repair Easy Anti-Cheat

4. Reinstall Halo

You can also uninstall Halo: MCC with third-party uninstaller software, some of which will more thoroughly erase leftover files, folders, and registry entries. SPONSORED ⇒ Get iOBit Uninstaller

6. Select the Repair option

Note: The above resolution is more specifically for the MS Store Halo: The Master Chief Collection game app.

7. Disable antivirus utilities before launching Halo: MCC

To disable third-party antivirus software, you’ll need to right-click the antivirus utility’s system tray icon to open a context menu for it. Then you can usually select some kind of disable option on most antivirus utilities’ context menus. Select to disable the antivirus shield for about an hour if you can. Note: If disabling antivirus software fixes the issue, it’s most likely that its shield is incorrectly flagging Easy Anti-Cheat or Halo: The Master Chief Collection. In which case, you can add Easy Anti Cheat or Halo: MCC to your antivirus utility’s white list to stop the false positive flagging.

8. Update Windows 10

Players have confirmed some of the fixes above can resolve the Invalid game executable error for Halo: The Master Chief Collection and other games. However, players who still need further potential fixes can submit a support ticket at the Halo Support website.
