UI demo error with Invoke activity

[brunodiaz (Bruno)]

Hi All,

I am new with the UIpath and currently sttrugling with the UI demo exercise.
Each time I run the secuence “UiDemoLogin” that calls the GetAppCredentials workflow, I get the below error:

Message: Cannot create unknown type ‘{http://schemas.uipath.com/workflow/activities}GetSecureCredential’.
Exception Type: System.Xaml.XamlObjectWriterException

I am not sure the reason of this error message. Could you please help?
I have checked some other topics but I could not find the solution.

Thank you in advance!

Do you have any suggestion about what it is missed?
Cheers!
