Hi Alain,
Many thanks for the quick response but perhaps I didn’t explain my problem well enough. When I export the executable I am able to install and run it on my home computer without problem. It is only when I transfer it to my work laptop that I have the problem. I have been able to create a single slide test case with just simple text, no movie or audio files, and this transfered and ran OK. I will try to export increasingly more complex presentations and try and find out at what point the problem occurs.
