Repairing Internet Explorer
First check that no-one has been playing with the settings! Launch Internet Explorer and select Tools >Internet Options >Advanced >Restore Defaults. Then close and reopen internet explorer. If its still playing up read on...
1. CLick start > run >type sfc /scannow {enter} and have your windows CD handy.
2. Search your hard drive for the "ie.inf" file (Usually in windows\inf\ or winnt\inf) When you have found it right click it and select install. Then reboot. [Running this from command line does the same "rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 %windir%\Inf\ie.inf"]
3. Still not working? CLick Start > settings >control Panel >Add/Remove Programs > internet explorer. Press the Change/Remove button (In windows 9X the button is Add/Remove). If youve upgraded IE you can revert to the previous version by selecting "Restore the previous Windows COnfiguration" but more often you will need "Repair Internet Explorer", then click OK. Reboot.
4. Still not working? CLick Start >Run >type regedit {enter} Navigate to the following key, HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ {89820200-ECBD-11cf-8B85-00AA005B4383} In the right hand pane find the value "IsInstalled" right click it, select modify, then change it to 0 (thats a Zero!).
You can now download and reinstall Internet Explorer (Links below).
NB. If you want to reinstall Outlook Express at the same time perform the same action on this registry key. HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ {44BBA840-CC51-11CF-AAFA-00AA00B6015C}
