I am trying to get a USB to Serial cable installed on Windows 7 (64-bit). Radio Shack Model: 26-949. The cable works fine in XP. I have tried Radio Shack, FTDI, Prolific drivers, but to no avail. When I try to load the drivers, it does not recognize the device. When I plug in the device, instead of comping up as a COM port, it shows up as 'Other Device USB-Serial Controller'.

Fineprint v9 incl key maker rar. I have completely restored Windows (re-formated hard drive, re-installed Windows), but none of the drivers I have found will work with Windows 7 (64-bit).
