Thanks for sharing the log.

ActivePresenter on Windows 7 only supports up to Full HD resolution (1920x1080) when exporting video. Please consider to reduce the output video resolution (select < 100% ratio or create smaller project) or upgrade to Windows 10 to resolve the issue.

Regards,

I used 1920x1080 but I have the same error that starts at recording start.
I don’ t the ability to upload video. if you enable me I’ll upload a video too.

Best regards

I have checked the log again and seen that a Windows Component is missing or failed to init on your computer (Warning: cannot initialize COM in MediaFoundation_Capture).
Please try updating Windows or:

  • Using the Flash Screen Video codec for recording.
  • Exporting to other formats (AVI, MKV).

Then, you can convert the exported videos to MP4 with Handbrake (https://handbrake.fr/) as a workaround.

Regards,

Active presenter works properly after total windows update at 1920x1080
Best regard

Thanks for your information. We are glad to hear that it works now.

Regards,
