Players have reported they can’t play Assassin’s Creed Mirage because that game doesn’t start on their PCs. For example, a player’s Reddit post described a Mirage startup issue like this, “I am having some trouble with launching Assassin’s Creed Mirage, and it’s been a headache this past 2 days since it always stays frozen before I actually get in the game (it shows the new Assassins symbol with smoke and then it just crashes with no error message).” This is how you can fix Assassin’s Creed Mirage not launching on a Windows PC.

Set Assassin’s Creed Mirage to Run as an Administrator
Another confirmed way to fix Assassin’s Creed Mirage not launching is to run that game with administrator rights.

Disable the Ubisoft Overlay
The Ubisoft client software includes an overlay feature for games. Some players confirm disabling that overly is an effective way to fix Assassin’s Creed Mirage not launching on Windows PCs. This is how you can disable the Ubisoft overly.
- Open the Ubisoft Connect software.
- Click the user profile in the Ubisoft software.
- Select Settings and Interface.
- Unselect the selected Enable in-game overlay for supported games setting.
The Enable in-game overly for supported games option
I also recommend disabling enabled overlays in another software package. For example, Steam, GeForce Experience, and Discord are third-party programs with overlays. Disable the overlays within all software packages installed on your PC that have them.
Edit the Resolution in the ACMirage File
A few players have said they’ve fixed Assassin’s Creed Mirage by changing resolution settings in the ACMirage file. Check if those settings are correctly set for your monitor’s max resolution and change them if they’re not. For example, those settings should be 1920 and 1080 for a full HD monitor (not 1280 x 720). These are the steps for editing the ACMirage configuration file.
- Open the Documents > Assassin’s Creed Documents folder in File Explorer.
- Right-click the ACMirage file to select Notepad on the Open with context menu.
- Next, look for the FullscreenWidth= and FullscreenHeight= settings in the ACMirage file.
- Change the FullscreenWidth and FullscreenHeight settings to your monitor’s recommended native resolution if set any differently. For example, set those settings to FullscreenWidth=1920 and FullscreenHeight=1080 for a full HD monitor.

Perform a Windows Clean Boot
There could be some background apps and services causing Assassin’s Creed Mirage startup issues on your PC. To minimize potential interference from conflicting third-party apps, try setting your Windows PC to clean boot. Applying a clean boot disables many third-party programs and services that automatically start in the background. Microsoft’s clean boot guide has full instructions for how to apply this potential fix.

Install a New GPU Driver
If your graphics card’s driver is old, you might need to install a new one to fix Assassin’s Creed Mirage not launching.

You can update your PC’s graphics driver as covered in this KeenGamer guide.
