Windows 7 - How to Target changes of IE under Program files and Program files (x86

Hi! Can anyone help?

There are 2 explorer.exe, one under program files and the other under program files (x86). Recently my ie8 homepage was hijacked, and this ie8 is under (x86). And every changes I made by Regedit are made on the other ie8 under normal program files and therefore cannot fix the problem.

When I give up fixing it and use ie8 under normal prgram files, the Adobe Flash Player cannot be installed. It seems that it automatically chooses to install under the (x86) ie8.

What can I do to target changes and installation to the specific ie8 I want?

Thanks!

Have you tried a repair install? Repair Install

Thanks for your reply!

I have not tried repair install, it seems it will reset a lot of things. I only want to reset the homepage of ie8 and enable Adobe Flash extension to be installed in ie8.

The problem is I can always reset the wrong ie8 (under normal program files) and install on the wrong ie8 (under x86 program files).
