I've got a problem I have never run into before. I have a Windows 7 PC that no matter what usb flash drive is plugged in no exe file on that flash drive will install without errors. I've tried multiple flash drives and multiple usb ports. The system recognizes the flash drive and can see all the files on it. I have reinstalled Windows 7 twice with all drivers and all updates. The only way I can install a program is to download it again and save it to the hard drive and install it from there. I can't install anything from the usb drive successfully. It almost has to be something interferring with the usb ports-maybe a problem with the bus-but I don't know how to troubleshoot it. If anyone has ever run into anything like this before I'd appreciate any input.
