I am going to go ahead and work with you on solving this problem as I
feel that we can come to a resolution. We may have to do a few
troubleshooting steps, so we'll use the "ask for clarification"
I figured that you would not be able to run REGEDIT as it is an
executable file and executable files are affected by the virus that
you were infected with. The first thing you need to do is to rename
your regedit.exe file to regedit.com. You can do this by using the
SEARCH feature from the Start Menu or you can go to a command prompt
and do the command :> ren regedit.exe regedit.com once you're in the
directory containing the file (usually C:\Windows, or C:\Winnt).
Now you can run regedit by typing REGEDIT.COM or just regedit in the
RUN box or from the command line. Once you are in the registry editor,
you need to browse to the following key:
The Default data for this key should ONLY read: "%1" %*
If it reads ANYTHING else, change it to the above. After this change
is made, reboot the system and see if you can run applications at this
Alternately, you can download the following file:
...and run it on your system. It will also make the changes I
mentioned above. It's for removing remnants of the SirCam virus, which
I suspect you had. Between these two solutions, it should take care of
this portion of your problem. If it fixes the problem, be sure to
rename your regedit back to .exe.
Please try them and report back to me on the results. Thanks!
FYI - Here's the complete removal instructions for the SirCam worm:

I think this is a Windows installer problem. I would recommend trying
to fully uninstall the Logitech webcam software and then re-install.
The Windows installer is very fickle when it comes to things being
"partially" removed. Usually, uninstalling and reinstalling things a
few times will correct the issues with the installed itself. If it
doesn't, let me know and I can point you to a couple of registry
entries that will probably clear up the problem.
Of course, if you do it through the registry, your webcam software or
whatever the installer is yelling about may not work 100% until it is
installed again correctly.
I'm glad we were able to fix your primary problem. One important thing
to remember in the future regarding viruses is to always make a note
of what viruses you are cleaning, especially if you are deleting
files. Also, many of today's viruses affect the registry and have
protection against simply having the infected file deleted as was in
this case. Try to do a little investigation on the virus before you
delete the file if you can. I've seen other viruses that cause the PC
not boot up any more when the file is deleted before registry entries
