It basically requires you to go into the Windows registry editor and change some values. Here’s how you can do it:

Open the Run Dialog Box by either pressing Win+R or searching for it using Windows search.
In the Run dialog box, type ‘regedit’ and hit the OK button. Doing this will open up a prompt asking for your permission to make changes to the registry. Click yes to access the Registry Editor.
Within the Registry Editor, expand the HKEY_LOCAL_MACHINE folder in the list to the left. Within that, expand the SOFTWARE folder.
In the Software section of the Registry editor, scroll down for a bit until you find the Microsoft section and expand that. Now go into Cryptography and right click MachineGuid.

Click on options and choose the Game Settings tab.
Once you’re in, tick the checkbox for the additional command line arguments.
