I uninstalled my previous version of SQL Nav, and uninstalled my PL/SQL Knowledge Xpert and my Oracle Admin Knowledge Xpert. Then installed SQL Nav 5.5, including the PL/SQL Knowledge Xpert. Then I ran SQL Nav. Opened a SQL Editor window, typed Select * from Dual, and ran it. Then I pressed for the Knowledge Xpert. I get the attached error message. Then when I press OK, the Search KX comes up. I can see that the Oracle Admin is the KX it is trying to search. I had uninstalled it, but I didn’t re-install it. Somehow, SQL Nav still thinks I have it.
The last time I used KX (before I uninstalled it), I was in the Oracle DBA KX. The uninstall does not clear that out.
