Windows 7: Acer Aspire M3460 Windows 7 64 bit coprocessor missing

Acer Aspire M3460 Windows 7 64 bit coprocessor missing

Hi another newbie here,

Just installed windows 7 pro 64bit to my machine and I have a driver error for coprocessor saying it is missing code 28.

I have gone through your forums and went to the acer site to download drivers. When I select make model and OS the only driver acer think I need (and offer) are the sound drivers which I installed anyway.

This however does not solve my issue.

I called acer support who passed the buck and said "contact windows"

I am not very technically minded when it comes to PCs can anyone provide me with a link to the driver I need so I can download the thing and install it.

A recap

My Machine Acer Aspire M3640 quad core
3GB Ram
Operating system windows 7 professional 64 bit.
