Windows 8 doesn't believe you. To actually make your [non-default-disabled-Administrator] account into an admin, you have to fully disable Metro using the secpol.msc Local Security editor.
To run a program in your Program Files folder as admin, you have to Right-click and Run as Administrator every time.
You can probably get away with just making the KoLmafia folder so that Everyone has Modify rights to it, rather than just Read rights.
Or you can put it onto Dropbox using those directions and since Dropbox runs from your personal profile, it should fix the permissions issues as well.
Or if you want to really confuse yourself, you can put it onto Dropbox and make a Directory Junction so that it looks like it's still in your Program Files folder, like I did.
But I'd suggest picking one of the first two options unless you have some command-line driven desire to see it in the familiar place. Heh.
Edit: Or if you have a pathologic hatred of Metro, I can give you step by step directions on how to fully disable it... but note that even the Microsoft Store will fail. It will still taunt you with its updates... you just won't be able to get any of them.
