With ED 9.52, the CAI "User Count User Details" window shows 4 columns to report CAI license usage.
There is Workstation, invoke2-API, Console: these are quite understandable but also "Registry" ?
So what does mean a check for a User ID in the Registry Column ?
We have been investigating this issue under support ticket 00705726.
If I understand correctly, it turns out that the Enterprise Dashboard was incorrectly counting an older 8.4 registry (Registry@nceprflisasrv0... in the screenshot).
We created a patch to prevent the check from appearing. As of today, we are waiting for the customer to validate the patch.
