Keyboard Driver Won't install  

I'm running an MS Digital Media Pro Keyboard (wired, PS2 connection) in my 64bit Win 7 machine. The qwerty keys work ok but the hot keys, custom keys, and the media controls will not work. When I go to the MS driver download site and install the correct drivers for a PS2 type of connection, the message comes up that this software cannot be installed because a later version of the USB driver is already loaded. I don't have a USB keyboard, I have a PS2 connection keyboard and nothing I do so far can fix this. I can't download the corrrect driver because it tells me that a later driver is already installed but for the wrong type of keyboard, and it advises me to plug in a USB keyboard. If I uninstall the current driver it is automatically reinstalled when I reboot. I'm stuck as to how to fix this. Any thoughts? Thanks!

Would it not be easier to connect it via USB? From what I can find about that keyboard it is native USB and connects via PS2 using an adapter.

Actually, MS says to not use an adapter for a PS2 connection. But I've got to confess that I found that I had done so and when I used a USB extension cord (My keyboard is far enough away from the computer) the problem went away. I had not seen the PS2 adapter way down under my desk and didn't realize it was there. So I have the native USB keyboard as you mention but had hooked it up wrong. Mea Culpa! Sorry to exercise everybody for my mistake!

OK, not to worry. It's easily done. Thanks for letting us know.
