Issue

User is unable to install or upgrade because of an "FK_Alarm_PQEventID" error at the "Create Databases" step.

Upon investigating the ION_Data.log you see the following: "The DELETE statement conflicted with the REFERENCE constraint "FK_Alarm_PQEventID". The conflict occurred in database "ION_Data", table "dbo.Alarm", column 'PQEventID'."
