In my cache studio i couldn't find the a namespace of iknow so how can i check is my studio version is compatible to to the one i am using now. If i don't have one then can be able to create a new namespace in studio?
Here's a way of discovering if your license includes the iKnow feature:
A return value of 1 indicates that you are licensed for iKnow. If the result is 0 then your license does not include iKnow.
See here for documentation about this method, which tells you that 11 is the feature number for iKnow.
Regarding namespaces, these are created in Portal, not in Studio. See this documentation.
