Symptoms

A SharePoint Workflow Integrated process does not want to deploy if you specify "InfoPath" as the "Forms Technology".
 

Diagnoses

Looking at the "Feature.xml" file in the "C:Program FilesCommon FilesMicrosoft SharedWeb Server Extensions14TEMPLATEFEATURESK2SPWorkflowIntegration" folder, the "" node under "" was missing.
 

Resolution

LABS provided an updated "feature.xml" file and that remedied the issue. If you run into this problem, please contact K2 support for the fix.
