Andrew,
thank you so much for your answer.
I’ve downloaded and installed version 22.1, but it’s still not working.
I can see the controls in the toolbox.

I added the references to new dlls, but the message about the licenses.licx file is there yet.
For the other hand, I’ve created a new form but when I try to add a control to it (ultraComboEditor), i get the following error message.

Thanks,
