Solution #7: Disable your antivirus temporarily

Antivirus programs are notorious for detecting false positives within the game’s update and installation files. As a result, the game’s patcher may not always launch successfully. The main reason these files are flagged as threats is that they are often installed on a device in a .ZIP format, which makes them quite difficult to open and scan.

By disabling your antivirus temporarily, you can resolve any errors you encounter while trying to launch the game. To temporarily disable your real-time protection with Windows Defender, follow the instructions below:

  1. Go to the Start menu and select Settings.
  2. Navigate to Update and Security and click Windows Security.
  3. Click Virus and Threat Protection and choose Manage Settings.
  4. Now, toggle off the switch next to the Real-Time Protection option.
  5. By this time, Windows Defender should be temporarily disabled. Should you wish to enable it again, just follow the steps above. But this time, toggle on the switch next to Real-Time Protection. Also, it is worth noting that if you have scheduled scans, they will still continue to run. But the files you have just downloaded or installed will not be scanned until the next scheduled scan.
  6. Once your antivirus has been disabled, try launching the game and see if the error message still shows.
