The plugins will give you the following resolutions to save your movie to:
Look on your drive for your Movie Maker 2.6 which will be in a location something like the following:
C:program filesMovie Maker
OR C:Program Files (x86)Movie Maker 2.6
Copy the prx files to the shared folder as follows…………
C:program filesMovie Makersharedprofiles
OR C:Program Files (x86)Movie Maker 2.6sharedprofiles
If the “profiles” folder does not exist then go ahead and create it.
