Same thing for me, disabling WIA worked after trying everything before that (i am an advanced user since 1985, i mean it haha) on Windows 7 X64 SP1.
There is an HP Deskjet F2280 machine installed here, WIA issues might rise due to that? edit: YES, read below. I have been trying to get the scanner to just scan (known problem in HP drivers that was not addressed for a long time and when they addressed it, it was not working again!!!!)
HP printer/scanner drivers are the worst thing in this planet: not properly working, disk/resources consuming bloatware.
Thanks for the solution. I hope the scanner can scan without WIA enabled...
edit: it is again freaking HP, read the solution here if you are unlucky or dumb
enough to have an HP printer/scanner product: http://www.realgeek.com/forums/solve...od-260644.html
