Inserting a new project within a project

Hi,

I created a project in Captivate 2019. In one of my slide, I created a button with the action to open another Captivate project, which is a software simulation I created which will serve as a Demo. In the "on success" field, I chose Open another project and selected the "Demo" I created and published. When I review my published final project and I click on my button to launch the demo, I get an error message. What am I doing wrong, I need your help! Thanks 🙂
