When I try to install the USB serial driver on my Windows 7 (x64) machine, I get a message saying "The driver could not be installed. Please close any open mbed drive windows and COM ports and try again."

The only program running is the installer and all explorer windows are closed (I rebooted just to make sure). My device is plugged in to the USB port (LED is illuminated).

I searched the forums - someone had the same problem under Vista, but apparently it was fixed. I didn't see anything about Windows 7 (apologies if I missed it).

I'm running mbedWinSerial_16466. Any idea what might be wrong?

Thanks in advance!

I had problem with usb audio code when it was not full retail copy of windows 7 I had lite version, change to full retail and everything worked.

Hmmm - I'm using the retail (non-OEM) version of Home Premium. I'm not sure if that's what you're thinking of as far as "lite" version?

no I meant a Stripped down version of windows 7.
