Error: The class installer has denied the request to install or upgrade this device

Just bought an Epson V30 scanner. Followed the instructions to install the software first on my notebook running Windows X Pro SP3 and then connect the scanner. Worked but the PDF function needed a newer version of the software. Downloaded the newer version from Epson's website and installed it. Didn't work - Find New Hardware Wizard ended with the error: The class installer has denied the request to install or upgrade this device.

Have tried uninstalling the software, rebooting and installation again but nothing works. Even tried uninstalling the USB drivers and reinstalling everything.

I tried installing the Epson software on a desktop computer and it works so it must be my notebook. I googled this problem and it seems to affect mainly scanners and other imaging devices but also some printers. No response from Epson so far.

The setupapi.log file is attached.

Any help?

    Just wanted to say thanks orangutang for your comment. A user of mine tried installing a scanner without admin rights and it fudged up his registry. When I logged in as admin and tried to install it I got this error. Your file fixed it beautifully.
