How do I uninstall Internet Explorer 8?

[Z]

I have a Windows XP computer. I recently upgraded from Internet Explorer 7 to Internet Explorer 8. Now my Favorites/Tools bar is gone. It just disappeared.

I can still right-click on my desktop. But I can no longer right-click anywhere on any web page. Nothing happens.

I tried the Alt key shortcuts. Nothing happens. I tried to left and right click in the grey area at the top of a web page. Nothing happens.

So I decided to uninstall IE8 and go back to IE7.

But the uninstaller stops, and asks me for the location of something called vgx.dll.000. I did a search and that file is not on my computer. So the IE8 uninstall will not finish.

Then I tried to reinstall IE8 from microsoft.com, but nothing happened. I even tried some Start-Run suggestions from the internet, but they did nothing.

I don't want to go to Chrome, etc. I just want my IE7 back. Please help!!!

Thanks!
