Diagnoses

It seems K2 for SharePoint is dependent on some specific fields in the Environment Library
 

Resolution

Please make sure that these two fields exist in your default Environment Library:

SmartForms Runtime SSL
SmartForms Designer Runtime SSL

Even if you don't use SSL, please still make sure the values of these fields are filled in and set to Default.

You can make sure that these values also exist in your String Tables, it will probably show up automatically after a K2 service restart.
