Since upgrading to Windows 10, I can no longer create .MP4 files from PowerPoint 2013. I have tried two different ways and either just hangs; no errors just never finishes even if left overnight. Tried:

1. Export/Create Video

2. Export/Change File Type

Have also tried to create .MWV file.  That also just hangs.

Hi,

Based on my test with my local environment (Windows 10 10240bulid & Office 2013 15.0.4745.1002 ), this feature is working fine. If you have not installed the latest Windows/Office update patches, please install them first.

Then, this issue might be caused by the third-party service, please try the following steps:

1> Press "Ctrl+Windows" key on keyboard for Run prompt.
2> Type "msconfig" and click on "OK"
3> Click on "Services" Tab and Click on "Hide all Microsoft Services"
4> Click on "Disable all" and Click on "Apply" & "Ok"
5> Click on "Restart"
6> Convert the file.
7> After conversion repeat the Steps 1 to 5 for enabling the services again.

If this issue still exists, please try to check the event log if there is any error message logged.

Hope it's helpful.

Regards,
