ITunes will not fully install, it says i need bonjour permission (windows 7 64 bit)

Question

I recently got my new desktop computer. It is an hp pavilion with Windows 7 64 bit operating system. I began adding on the programs i wanted on my computer after starting it up a few days ago and found that everytime i try to download iTunes (64 bit) for windows it makes it through almost the whole process before it tell sme there was an error with ProgramFIles(x86) Bonjour mDNSResponder and something about how i may require permissions, i have gone on many websites trying to find the solution to my problem. I found out how to change the permissions on programs but when i try to do that to Bonjour it tells me i dont have the proper permissions to even get into the security settings. Please Help, i have been without a computer for several months which has gotten in the way of my iPod updating and all around music/movie enjoyment

That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?
