Hello experts.

I migrated a project with a CPU 416 to a CPU 410-5H (PCS7 v7.1 to v8.1 SP1).
The project has a WinCC Appl and a WinCC Appl Ref..

I have already downloaded the program to CPU 410-5H and WinCC Appl is working correctly.

When I try to download to the PC with the WinCC referenced it shows an error:

"The project could not be opened. Database context does not exist or ..."

I also delete the WinCC Appl Ref, adding a new one into the multiproject and try it to download with the same error.

Any ideas.

Thank you in advance for your help

 Hi!
Which steps/instructions did you follow to create the WinCC Appl Ref ??
