I have upgraded DLO AGENT from DLO 7.0 TO DLO 7.5 , i got the error "Access denied. Failed to create recovery key" So when i took support from symantec , they give reference to DLO 7.5 Admin guide
When I upgrade the Desktop Agent from 7.0 to 7.5 by using a different user account (instead of
the administrator account that was used to log on to the machine and install Desktop Agent 7.0
version), and when I try to access the existing desktop user data folder, the Desktop Agent goes
to disabled state with the following error: “Access denied. Failed to create recovery key.”
The error occurs because the user account may not have the privileges to access the existing
desktop user data folder.
To resolve this issue, follow these steps:
1 Right-click the desktop user data folder, and select Properties.
2 Select the Security tab and add the user account.
3 Click Apply.
The recovery key is created.
So one must read DLO 7.5 ADMIN Guide after upgrading
