Hi, and welcome to the board.
Try this:
Create a new Text file on you desktop, and paste the following bold text into it:
REGEDIT4
[-HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Plugins\Extension]
Save as Extension.reg
Doubleclick it, and answer 'yes' when asked whether you want to merge the contents of the file into the registry.
Reboot.
This ought to solve your problem.
Good luck,
