Sibelius not exporting files as mp3

[Jakewhitla]

Hi Everyone,
I hope you all are well.

I recently downloaded the most recent version of Sibelius onto my computer and I made a quick song so that I can try exporting it in all the different ways Sibelius offers as a test. Every mode of exporting has been successful except for exporting as an mp3 file. When I try to export the file, the export button at the bottom is greyed out and I am unable to click it. The following message also shows up under the playback configuration. It says "You can't use this playback configuration for exporting audio because it does not contain any virtual instruments. Please chose another playback configuration above".
Not sure where to go from here, any help would be very welcome.

I am running Sibelius on my laptop witch uses windows 10.

You cannot export audio if your only playback device is General MIDI.

Install (or, if already installed, choose a configuration) that uses Sibelius Sounds.

I have not instaled Sibelius Sounds. I'll do that and check back.

Thanks for the reply!

Thanks so much Mike. It worked, I can now export mp3 files!
