Cannot install IE9 32bit on 64bit W7 OS! Really need help after virus!

So I removed a virus infection in ie9 32 bit by replacing the whole internet explorer folder from program files (x86) with the internet explorer folder from the 64 bit program files.
Now I need to compile projects in Visual Studio , the program needs the 32 bit version of ieproxy.dll but when I add the 32bit backed up version I cannot browse the internet, IE won't even startup at all! So I replaced it back, I don't have a system restore point from before the 'shit'. Also using 'turn windows features on or off' doesn't seem to fix my browser problem, it remains 64bit.

I have downloaded the 32bit installer but it says the 64bit OS is not supported! What the Heck? ! So I extracted the contents of the package with Universal Extractor but it's a huge mess.. I don't know what to copy and paste etc.. about a few hundred thousanmd dll inf and exe files just to install ie9 32bit?

Edit:
Also I did run "sfc /scannow" to remove the virus from my computer, but IE9 32 bit still remained infected! conclusion: sfc does not repair IE.
addition : I also ran sfc /scannow to remove the virus from my system but IE9 remained affected, that is why I did the above steps!

Please help me out, can somebody upload their %program files (x86)%/Internet Explorer/ directory, please? (internet explorer 9 ofcourse).

Thanks in advance.

For 64-bit systems, you need to download and install the 64-bit version of IE9. The 64-bit version also includes the 32-bit edition, and both will be installed.

Download Internet Explorer 9 - Microsoft Windows
