Can't upgrade from BackupExec 2010 R3 to 2012 due to deduplication option
I'm triying to upgrade my Backup Exec 2010 R3 server to Backup Exec 2012.
Upgrade installation fails beacuse I have installed "Deduplication option" so I must uninstall it first (in fact I've never used this option, I've just installed it for testing purposes).
The problem is that I can't uninstall this option. It appears ticked (installed) but I can't uninstall it in order to launch the upgrade process.
Any ideas ?
Thanks in advance
