Upgrading from version 8.2 or later

As of UC Diagnostics 8.3, Exchange 2000 and Exchange 2003 are not supported. If you are upgrading from UC Diagnostics 8.2, use the Force Discovery Now option to repopulate your topology view.

UC Diagnostics 8.4.1 was rebranded to the Quest company name and the installation path is now Quest. After you upgrade from 8.2, 8.3 or 8.4 to the current version, the Save As Template and Save As (Drilldown/AlarmLog) dialogs might still point to the previous installation path since Windows saved the path in the registry.

Workaround

You must manually redirect and save to the new default Quest path such as "%current_user%\AppData\Roaming\Quest\Shared\Templates".
