Having trouble installing disc for Brother DCP-350C. Please Help :/

I'm trying to install the disc that came with my Brother DCP-350C printer. When I try to install it I get the error message:
(( MFL-Pro Suite can not continue this installation because PaperPort(TM)11SE requires the latest windows (R) Service Pack)))
I have Windows 7 installed on my computer. I have uninstalled the version of paperport 11 I had off of my computer, and downloaded the paperport11 setup that came with the disk, I'm still getting the same error message. Can someone please help, Thanks Much :).
