Corrupted export and HTML5 Preview when deleting Mouse Click Sound

Hello Atomi Support and Community,

please have a look at the enclosed files. I reproduced my issue in a simple project with 4 slides, in reality i made an massive effort to find the reason for that.

After deleting the last remaining Mouse Click Sound (None instead Default Mouse Click 1) the preview as well as the export in HTML5 is not working correctly. (see corrupted export and preview when removing Mouse Click 1.approj)

For reference you can use the second file (see Bug fixed.approj) with the Defaul Mouse Click 1. Everything is fine.

Maybe you know if it is a bug or just an error for my part?

Thanks in advance and best regards,

ActivePresenter Version: 7.2.5

Thanks. I sent you an E-Mail.

Hi Marcel,
We confirm it is a bug in ActivePresenter 7.2.5. We will try to release a fix soon.
In the meantime, please use a silence sound instead as a workaround.
We are sorry for this inconvenience.

thank you for the prompt reply. Another workaround is to use a “fake mouse click” in the project. Just define a invisible Mouse Click Interaction anywhere on a slide.
