Hi,Not trying to resurrect old threads, but I'm gonna reply anyways since this thread came on top of the search results list when I searched for "you require permission from SYSTEM"; hopefully this'll help everybody.
Here's How to Enable permission and get-around that stoopid "require permission from System .."
1. Download TakeOwnership
2. Open and Click on "InstallTakeOwnership.reg"
4. Right-Click on your selected Folder and choose "Take OwnerShip"
5. Press Del to Remove your desired Folder.
