I've done it! I can finally play SP again
I didn't try giving full control to Users (I thought I didn't have to because I am the admin
)
Add this to your guide:
For those using Vista that get an IOProtect error, there is an easy fix. You will need an administrator account on your computer in order to do this. Go to ioprotect.exe in your SurvivalProject folder and right-click it, then go to Properties. Click on the Security tab and give full control to SYSTEM, Administrators, and Users, that should stop giving the error.
