Cannot install F4280 All-in-One in Windows Vista 32 bit

Question

I downloaded the latest driver and full feature software but I get a screen that says there is a newer version of the software already installed.  Any ideas are greatly appreciated (except buying a new printer).

Answer 1

I tried each step but no cigar.  Some files were found to be corrupted and almost all were fixed by running the MS diagnostic tools you suggested.  I have provided some information from the sfc.txt file below that may be the root cause but I am not software savvy to the point of understanding what the information is actually telling me.

I still can't seem to completely get the program files uninstalled or reinstalled.  What file does the software check when detecting the current software installation status?  If I had that information, I might be able to find a way to remove it or modify it to allow the new installation.  I am at a loss.  I know that there has to be a way to resolve this but I am still a novice when it comes to the software.
