I recently found a portable version of Internet Explorer and tried running it. Nothing happened when I opened up the portable version, except now I was unable to open up the normal version on my hard drive. I need some suggestions on what to do, i will list everything that i have tried so far below. Thank you I have Windows Vista Home Premium running on this notebook, Firefox works fine but IE doesn't open at all. Tried doing the following: Downloading and reinstalling IE 8, Uninstalling IE 8 , Running sfc /scannow, System Restore doesn't go back that far unfortunately, Removing BHOs with HiJackthis, and all of those did not work. Please let me know what i should try, thanks!
