Hi , 

I received a wincc comfort project but I have an wincc basic installed on my pc.
I could retrieve project but know I can't open screens that have been made in this project ...

Hello,

When you have WinCC Basic, you can only use Basic panels.

When you have a WinCC Comfort project (Comfort panel), you will need WinCC Comfort to open this project.

Best regards,
