Add the Recording Tab to PowerPoint Not Working

While the recording tab is not available, in the version my work uses most of the features are still available. 

Under the "Insert" tab you can add screen recordings and audio to go with the slides as one option. 

Under the "slide show" tab you can select 'Record Slide Show' - this does allow recording of the timing, Audio and use of the laser/pointer etc and to play the pre-recorded video's/audio for timing that added been added from the insert tab. 

Then simply go File>export>Create Video and save it to a location ready to upload.

Hope that is a helpful work around.
