Can't Export Animation into Movie

Just as the title says. I have a small scale animation, no more than 67 frames but every time I click on Export, Movie, then enter a name and destination it doesn’t show up. I can only find the file by going to recent files and then it refuses to open. I am using a trial, but I’d think that I’d still be able to export projects, right?

Is there anyone who can help? Or is this how the trials are?

If you’re on Windows, you need to have Quicktime installed in
order to export to movie format.

Beyond that, verify that the location you are exporting to is one
that your logged-in user has the rights to write to such as your desktop
or your documents folder. There is a button showing “…” that you can
click to browse to the location you wish to save to.
