TIA Openness Demo - TIA protal without project connected

Hi to All,

I am using TIA openness on several PCs, and only on the one, I have a problem when I want to connect to an already opened project from the TIA Openness Demo app. I am receiving the message "TIA Portal without project connected". 

How to fix it?

Hello makijato,

check whether you have installed all necessary optional package on your PC. Check also the necessary HSPs which you needed you for your project. You cannot use your TIA Portal project with TIA Portal Openness if required HSPs are not installed.

It looks like I have all the necessary HSPs. But you gave me a new direction to look for a problem. I created a new simple project, and the openness demo app. wanted to open it. So I could conclude the problem is in my project, not openness.

Thanks!
