How to uninstall and re-install Movie Maker

Split from this thread.

Below are the steps on how to uninstall Windows Live Essentials via CMD line parameter.

a. Go to Start ->All Programs ->Accessories

b. Right click on Command Prompt and select Run as Administrator

c. Run the following commands to uninstall Windows Live Essentials:

· (64 bit) "c:\program files (x86)\windows live\installer\wlarp.exe" /cleanup:all /q

· (32 bit) "c:\program files\windows live\installer\wlarp.exe" /cleanup:all /q

d. A dialog box shows status until uninstallation has completed

I've seen a few people with this problem, but no answers:

When I type the command prompt, I get the message "The system cannot find the path specified."

I've been trying for months to uninstall these programs so I can reinstall Movie Maker. I currently have Photo Gallery but cannot find a way to uninstall it. Windows Live Essentials doesn't appear in the programs to uninstall via Control Panel. 

This problem originated when I deleted all files associated with Movie Maker, and my computer deleted them permanently without sending them to the recycle bin. I'd appreciate some help with this.
