Fix 2 – Update your graphics driver

The wrong or out of date graphics driver may completely ruin the gameplay experience of Mafia Definitive Edition. If you expect the game to run at the first-class condition, it’s essential that you have the latest driver for your GPU.

There are two ways you can update the graphics driver: manually or automatically.

Option 1 – Download and install the driver manually

Graphics card manufacturers such as NVIDIA and AMD keep updating drivers. To get them, you need to go to their official websites, find the drivers corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually.

Once you’ve downloaded the correct drivers for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.

Option 2 – Automatically update the graphics drivers

If you don’t have the time, patience or computer skills to update the graphics driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks:

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to the flagged graphics driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)

You can do it for free if you like, but it’s partly manual.
The Pro version of Driver Easy comes with full technical support.
If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

Fix 3 – Run the mafiadefinitiveedition.exe file

If you cannot open Mafia Definitive Edition the right way, a simple workaround is to launch the mafiadefinitiveedition.exe file and disable launcher in settings. Here’s how:

1) Open Steam. Then, click the Library tab.

2) Right-click Mafia: Definitive Edition from the game list and click Manage. Then, click Browse local files.

If you’re using Epic Games Launcher, generally you can find the game’s installation folder here: C.\Program Files\Epic Games\[Game name]

3) Double-click the mafiadefinitiveedition.exe file instead of the launcher.exe file to start the game.

4) Click Options.

5) Click Game.

6) Turn on Disable Launcher.

Relaunch Mafia Definitive Edition and see if the not-launching issue is resolved. If this doesn’t work unfortunately, please proceed to the next fix.


Fix 4 – Run Mafia Definitive Edition and game launcher as an administrator

Some games require additional access to the Windows files before they can launch and operate properly. To allow the necessary permissions for Mafia Definitive Edition, it’s suggested you run the game and game launcher as an administrator.

1) Right-click the mafiadefinitiveedition.exe file and click Properties.

2) Click the Compatibility tab, and then check the box next to Run this program as an administrator.

3) Click OK.

You also need to grant the game launcher administrator rights as follows:

4) Right-click your game launcher (Steam or Epic Games Launcher) and click Properties.

5) Select the Compatability tab. Then, tick Run this program as an administrator and click OK.

Now relaunch the game to test if this method works. Still no luck? No worries, there are two more fixes to try.


Fix 5 – Verify the integrity of your game files

Missing or corrupted game file is also one of the possible causes of your Mafia Definitive Edition not launching problem. You can simply use the built-in repair tool to fix it:

Steam

Epic Games Launcher

On Steam

1) Open Steam, and select the Library tab.

2) Right-click Mafia Definitive Edition from the game list, and click Properties.

3) Click the Local Files tab, and click Verify the integrity of game files.

Fix 6 – Temporarily disable your antivirus

Many users install antivirus to protect their computers from potential threats or attacks. If you do too, you should pay attention that whether the antivirus identifies your game as malware by mistake and blocks it from launching.

Turn off the antivirus for a while and see if the game is able to start. If yes, you need to whitelist Mafia Definitive Edition so that you can use both without trouble.

Be extra careful about what sites you visit, what emails you open and what files you download when your antivirus is disabled.
