So I can not install the Troll Trouble DLC. I preordered and registered my game. I have downloaded the DLC yet when ever I hit install it always displays a Launcher error that says "Administrator privileges required for activation" I am the only account on this computer and I have administrator privileges.

Anyone know what can be going wrong?

Try launching the launcher.exe while holding SHIFT and select Execute program as Administrator.

Maybe It'll solve your problem... maybe not :P

That did the trick, Thank you very much.
