Before you open up windows movie maker.. (the program) right click on the icon and choose the setting "run as administrator" then once the program opens up, you should be able to add whatever add on you wish...
Didn't work
The instructions I got from youtube are this.
Copy and paste code in notebook then "save as" pick "computer" pick 'C: drive" Pick "program files" pick "movie maker" pick "shared" pick "addonTFX" then name file "bluescreen.xml" but I am getting that permission thing I mentioned before.
Is there something I'm doing wrong or another method? Once I open the program like instructed above by Turbo what next?
