Method 5: Disable Antivirus

Your Antivirus is one of your best friends while using your computer. It protects you on a real-time basis from viruses, malware, Trojans, and all the other malicious software across the globe. It also helps you to block popup ads while browsing the internet. But sometimes, it fails to understand the difference between friend and foe and blocks off harmless applications, especially games like Mafia Definitive Edition.

To identify if this is the case, you need to:

  • Disable your Antivirus for a few minutes and try and launch the game to see if it works fine. Note: When your antivirus is disabled, do not browse the internet or open your emails.
  • If your antivirus is the culprit, add an exception in your Antivirus for the mafiadefinitiveedition.exe game file, which means your antivirus will not scan it.

These are the two steps you need to perform if your antivirus is blocking you to launch Mafia Definitive Edition.

Method 6: Update Graphic Drivers

A graphic driver is a small program developed by the OEM graphic card manufacturer that communicates between the Operating System and the Monitor screen. All the fantastic graphics and distinctive colors are due to these drivers. The Graphic card has a significant role to play, of course, but even a 2 GB graphics card would act as a simple VGA card if correct drivers are not installed. There are three ways to update graphic card drivers:

Option 1: Use The Official website

All Graphic card manufacturers have an official website where you can find updated drivers stored and available for download. If you know the model and version of your hardware, you can search for your card driver and download it. After downloading it, you can install it by launching the file and following the on-screen instructions.

Option 2: Use The Device Manager

Microsoft has inculcated an inbuilt tool for updating drivers automatically. It is known as the Device Manager and scans your computer for hardware connected and then searches for updated drivers on Microsoft Servers. Here are the steps to use the Device Manager:

Step 1: Press the Windows and R keys and type “devmgmt.msc” in the Run Box.

Step 2: Press the OK button and then look for the Display Adapters in the list and click on it. Choose your graphic card and make a right-click on it.

Step 3: From the context menu, select Update Drivers and carry out the on-screen instructions to complete the process.
