Can't install hotkey OSD on windows 7 T61.

[RoafBeast]

I installed windows 7 64 bit again and now I can't install the hotkey OSD. At first I used the Lenovo system update and it didn't work. I restored to before installing anything and tried manual installation and still nothing. I also tried older versions. I get "An error occurred while copying file shtctky.dll. Cannot copy file to destination directory."

It's driving me crazy. Before formatting it worked fine. After that it won't install. I haven't changed anything in the bios (not the middleton bios). I tried following exactly what I did the first time but still nothing.
