NetBackup is not supported on hosts with Backup Exec installed

Problem

NetBackup is not supported on Windows hosts which also have Backup Exec installed.

• Conflicts between these products will produce severe system issues.
• Backup Exec and NetBackup should not be installed to the same host.
• These products have not been designed to coexist, and severe system issues occur when they are installed on the same system. 
• You must uninstall the existing product before installing the other.
• This applies to RHEL and any OS platforms where Backup Exec is supported.

If Backup Exec is installed the preinstall check will fail with an error "not ok be_nb_same_host: Backup Exec is installed"
 

Error Message

not ok be_nb_same_host: Backup Exec is installed

Solution

1. Uninstall both products using the Programs and Features (Add/Remove Programs) console in the Windows control panel.
2. Uninstall any C++ Redistributable packages that were deployed automatically during the Backup Exec installation Process.
3. In some cases, you may need to manually remove the product folders. 

• These folders normally reside in C:\Program Files\Symantec and C:\Program Files\Veritas.
• If you are using other Veritas Products (such as AntiVirus), do not remove it's folder under C:\Program Files\Symantec.  
• You may also need to manually remove product registry keys at HKEY_LOCAL_MACHINE\SOFTWARE\Symantec and  HKEY_LOCAL_MACHINE\SOFTWARE\Veritas. 
• You may also need to manually remove the BackupExec agent service using the OS command "sc delete BackupExecAgentAccelerator"

4. Reinstall the desired product only.
5. Reboot the machine.
