How do I install the scan feature on the right click menu

I love spybot and it has rescued me in more than one occasion. One feature was the right-click scan feature that allowed you to scan individual drives or files. I have this feature on my laptop but not on my home system. How do I install this feature? Thanks.

See if this works:
Go to Start,then Run.
(Or,if using Vista,go to Start,type in Run,and double click it.)
Copy and Paste in "C:\Program Files\Spybot - Search & Destroy\SDFiles.exe" /REGSERVER and hit ok.

The above worked for me at first *I think*,but then I had to go and make things more complicated,so let me know if it doesn't work. :p:

I don't think rightclick scanning is available by default on the newer version of Spybot,so you might want to check to see if you have the latest version of Spybot on your home system :)
