DLL dilema

*dilemma

One or more of my .dll's are corrupted- I cannot install chrome or internet explorer. This is the error I get when installing either:


This URL Dpx.dll Analysis Report
says the dpx.dll is a
"Microsoft Delta Package Expander - Dpx.dll is a 32/64-bit Dynamic Linked Library of code components for a graphics UI style application."

It is linked to other .dll's, so it may or may not be that particular DLL. I have replaced the file "expand.exe," but I cannot find a version of dpx.dll on the web that matches the version I have (6.1.7600.16385).
I downloaded a windows disc from a torrent, but I assume that because it was the "Ultimate" version while mine is the "Premium" version, I couldn't "Upgrade" (Which I believe would replace system32 without deleting everything). The "Premium" torrent has few seeds with the download speed ~1kbs.

I have tried dozens of articles that attempted to fix the problem. The time I have spent on this problem is ridiculous, but I want to see this through.

My questions are:
1) Can anyone provide me with the Win 7 X64 version of dpx.dll?
2) Is it possible to copy over someone else's entire Win7 X64 system32 folder and replace mine with it?

Thanks in advance for any advice

 

From my system, version matches but not sure if this will do it for you........

Thanks TANWare. As fate would have it, my excessive tinkering with things I don't quite understand has made the notification show up on boot and periodically through the day, rather than only when I try to install IE9 & Chrome. Ahh, life
