Cause
The setup program cannot assign the necessary rights to existing account(s).
Solution
Add the necessary rights to the user account manually. See appropriate section:
For "Failed to grant privilege to user"
After adding the necessary rights, reattempt the installation.
For "Failed to add user to group 'Backup Operators'"
Manually add the affected user to the "Backup Operators" group:
Click Search, type in compmgmt.msc and press Enter.
Computer Management opens. Navigate to Local Users and Groups, click Groups, then double-click Backup Operators on in the right hand side.
In the Properties window, click Add.
In Enter the object names to select, type the affected user' username and click Check names.
