If for some reason you actually want to do this...
It requires some permission editing (I haven't made it so it gives itself permissions yet)
Step 1: Download the code and install the mod and shit. If you dont know how to do this please go to the Steammodded page.
Step 2: Go to C:\Windows and... bear with me here
Step 3: Right click on System32, go to properties and then the security tab.
Step 4: Click on Advanced and then Change (Next to Owner: TrustedInstaller)
Step 5: Put 'Administrators' in the object name then click 'Check Names'
Step 6: Then press okay and apply or whatever and stuff. A window should pop up and if there are any errors probably disregard them it should be okaaaay
Step 7: Edit permissions and allow full control to Users (If this doesn't work then just give everything permissions)
Step 8: Click apply and launch the mod. And hopefully you're doing this on a virtual machine because god cant save you now
