APM 2.6 windows 8 driver installation

Has anyone had problems installing the drivers for the APM 2.6 on a windows 8 machine? I have tried a few times and i get getting the following error:

“windows found the device driver software but encounter an error while trying to install it”

It recommends going to the device website and downloading the drivers. I have repeated this a few times…

Any suggestions?

I had the same problem. See the following post for solution
