Can't open sound fonts with Musescore

I am using the mac computer my school issued me, and I can't install applications without an administrator password, so when my computer prompted me to move Musescore to the Applications folder, I put it in a different folder instead. It works, but the computer doesn't realize it's an app, and won't let me open sound fonts with it, so they don't make any sound. Is there some other way I can open them, or do I have to get an administrator to download the app legitimately?
