The software environment includes Creator 4.2/4.4 and other versions. There is also Dock SDK3.3.
It used to be possible to edit DMC projects. Now I find that it can't be opened.
Such as the prompt content of the attachment.
What dependency packages need to be installed for DMC support?
I was able to the open the DMC project from the Dock SDK on PSoC Creator 4.4. Please install the latest version of the Dock SDK from- https://www.cypress.com/documentation/reference-designs/ez-pd-ccgx-usb-type-c-monitordock-solution
Please also let me know if you are able to open the CCG4 Dock workspace if not the DMC project separately?
Please provide more details of the steps you tried? As per the Dock SDK firmware User Guide, it should be possible to open CCG4_DOCK_REV05.cywrk with PSoC Creator 4.2- please try the same.
