I was working through the K2 Training Exercise and got to the workflow deployment. When I chose to deploy, the deployment failed.  Has anyone else experienced this or can someone help?  I'm working with version 4.7.  Here is the failed text:

System.IO.FileNotFoundException: Could not load file or assembly 'SourceCode.Workflow.Design.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=16a2c5aaaa1b130d' or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value yHKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value yHKLMSoftwareMicrosoftFusion!EnableLog].

Thanks for any help someone can offer.
