Exporting not working

I keep trying to export my video but nothing happens when I click ‘ok’, and I can’t open video options beforehand either, I can export as an SWF file but my computer can’t open it.

I feel like I’m missing something really obvious, I’m only on the trial right now but I didn’t think that would make a difference?

You may have neglected to install Quicktime.
Install the Quicktime Player and reboot - then try it again.

I’m having trouble in the exact same manner. .mov doesn’t save in the directory I tell it to and none of the options will open. I’m on Windows 8.1, with quicktime installed and a monthly sub service. Kinda need this to work for school.
