Jimmy, need some clarification on the last post.

Are saying you installed dotnetnuke twice, each with different object qualifiers using the same database? And the second install failed?

There is a foreign key constraint between the EventLog and EventLogTypes table.  If DNN tries to insert an EventLog entry and the EventLogType is not in the EventLogType table, then it will throw this error above.  To see which EventLogType is missing from the EventLogTypes table, you can temporarily remove that table constraint that is causing the problem.  Of course, don't do this in production...make sure it's a test database that's backed up.

Then you can try the install again, and it will insert into the EventLog table the event log entries that it was failing to create the first time.  This doesn't SOLVE the problem - but it lets you see more information about the root of the problem.
