I upgraded from xp to windows 7, i had a problem with sound but have fixed it now. I also have a problem with my scanner. I have a pixma mp830. When I try and open up the program I get a message that says the scanner driver supported by this software is not installed, install it then retry. I have been onto the canon website and installed the new driver but I still keep getting the same message. With all the problems I keep having after upgrading I am beginning to think I was better off with xp. Can someone pleaaaaaaaaaaaase help.
