Upgrades to Backup Exec 2010 fail with "FATAL ERROR: Error 1606. Could not access network location \IDR\Data."
The above failure occurs on systems that were previously upgraded from another version of Backup Exec. The issue is caused by the Microsoft's Installer (MSI) database listing multiple installations of Backup Exec, which causes the 2010 installer to default to the older version of Backup Exec when looking for the upgrade files.
