Which is the best version control tool for Clarion 11 app?

I have been getting my machine configured with several “flavors” of v11 of clarion.
basically The base Version v11, and 2 additional copies tailored for a clients specific needs


So I was under the impression that when you set the clarion version it used the clarion BIN/libsrc etc defined int he option for that version. I have different Template needs for each client and when I register templates for the specific client version it always updates the primary base v11 version of the registry.

How can i make it update and use the registry for the version that is active?

I am sure I have missed something.
