FYI, if you changed your downloads folder for your browser, it will be located in that directory.

Step 3: Right click on BG3ModManager.zip and choose Extract All...

Step 4: Click on Extract and this will extract into your Downloads folder.

It does not matter where you extract this to, but I would suggest keeping it simple and extracting it into your Downloads folder.

Step 5: Wait for the files to extract.

Step 6: You will now have the folder for BG3ModManager open up.

Step 7: Right-click on BG3ModManager.exe and Run as administrator.

Step 8: You will get a User Account Control prompt. Accept it by clicking on Yes.

Step 9: The game should detect the path to the game folder for Steam.

Step 10: If the game does not detect the path to the game folder and pops up with this, navigate to your Steam games directory.

Step 11: Now we are going to import the Party Limit Begone Mod. Click on File > Import Mod...

Step 12: Navigate to your Downloads folder and choose the Party Limit Begone.zip file. Once you have clicked on the zip folder, click on Open.

Step 13: Once it is done importing, confirm it imported by checking here:

Step 14: If it is on the right of the Mod Manager window, drag it to the left so it is in the Active Mods list.

Step 15: Next click on Tools > Download & Extract the Script Extender...

Step 16: Confirm installing the Script Extender by clicking on Yes here.

Step 17: You should get this message at the bottom left of the Mod Manager window to confirm the successful installation of Script Extender.

Step 18: After this, test launching the game by clicking on Go > Launch Game

Step 19: If you get this redirect popup to Steam, make sure to click Continue.

Step 20: Hopefully it worked, if not, I might have to help you troubleshoot, lol.

Step 1: Tap the Windows Key on your keyboard and type in run. Open it.

Step 2: Type in %AppData%

Step 3: Navigate back a folder by clicking on AppData.

Step 4: Click on the Local folder.

Step 5: Scroll down and click on the Marvel folder.

Step 6: Click on the Saved folder.

Step 7: Click on the Config folder.

Step 8: Click on the Windows folder.

Step 9: Right click the GameUserSettings.ini file and click on Edit.

Step 10: Scroll to the bottom of the config file and copy and paste the following text:

[/Script/Engine.InputSettings]
bEnableMouseSmoothing=False
bViewAccelerationEnabled=False

Step 11: Save the config file and close the Notepad window.

Step 12: Right click the GameUserSettings.ini file again and click on Properties.

Step 13: Turn on the "Read-only" attribute at the bottom of the popup. 

Step 14: Now click on Apply in the bottom right side and click OK.

Step 15: That's it! You are done and ready to play the game! The reason why you make it read-only is so Marvel Rivals dev's don't undo what you just did! :)
