I'm sorry about that, it's that the setup fails to start the LazSqlX (checkbox on last setup pages "Launch Program"), because it doesn't have the permission by OS to run programs, though I've checked the option "Requires elevated privileges" but it seems it won't work without "Run as admin" so maybe I should remove the "Launch LazSqlX" checkbox after setup finishes
Did you try on Connection form to switch DbEngine to Zeos and then see if you can connect?
