Windows 7 Cannot install IIS (or any other feature I try)

Hi All,

When I go into Turn Windows Features on or off and select the various IIS components I require it goes away and the progress bar gets to 99% before I get a message saying. "An error has occurred. Not all of the features were successfully changed." If I look in the CBS.LOG file I can see it installs just about everything OK before getting to a point were the attached log takes place. As you can see, the error seems to come from an interface in sppinst.dll but I'm really not sure what is going on. A bit more info. I get errors when I switch on any features, not just IIS but it is always around spp installer. I need IIS to work and this is really frustrating me! Help! Oh yes, I've tried this as Administrator etc but with no joy.

Many thanks
