I loaded IE7 Beta2 to computer, then had problems with motherboard. Supplier repaired Windows XP to fix drivers for motjherboard. I am now unable to access Internet Explorer. It seems that the file wininet.dll has been overwritted with an older version. When I try to reload IE7, I am told that ie7 is already loaded and that I should remove it through the Control Panel. However, i5t no longer appears in the Control Panel. Is there a way I can force a reload of IE7 Beta2? I assume there should be a registry key change which will let me do this.
