Troubleshooting
Installation Issues
1. Can I use DPPO on my non-Dell laptop or desktop?
No. DPPO software has been especially designed to optimize the performance of your Dell machine. DPPO will not
run on any non-Dell system.
2. Why does DPPO installer fail with a message saying my system is not supported?
DPPO will not install on operating systems other than Windows 7 or Windows 8. Windows Vista or earlier versions
are not supported.
3. Why does DPPO installer fail with a message saying Dell Data Vault software is already installed?
DPPO includes a copy of Dell Data Vault in the installation package. If another copy of Dell Data Vault is found to
be pre-installed, DPPO installer will abort. Please uninstall Dell Data Vault before attempting to install DPPO again.
Home Page
1. Why don’t I see the Graphics Utilization bar on the home page of DPPO application?
This is not a cause for concern. Graphics utilization is not available on some Dell systems. Based on the
configuration of your system, this data may not be available.
Profiles & Policies
1. Why do I see “Policy needs reboot” message?
Some of the DPPO policies change system attributes that require a reboot before the changes can take effect.
When this happens the user is informed and given an opportunity to reboot the system. You can decide to reboot
later but the changes applied to your system will become effective only after you reboot. Some examples of
policies that require reboot are those that change Processor Hyper-Threading, Processor Cores etc.
2. Why do I see “Policy needs application restart” message?
Some of the DPPO policies change system attributes that require the ISV application to be restarted before the
changes can take effect. When this happens the user is informed and given an opportunity to restart the ISV
application. You can decide to continue using the application but the changes applied to your system will become
effective only the next time the application is started. Some examples of policies that require application restart
are those that change Nvidia settings.
3. Why do I see “Policy conflict occurred” message?
You may have two different active profiles that contain policies that change the same system attribute to different
values. When such a situation is detected by DPPO, one the policies is aborted and the user is notified. DPPO
determines a policy conflict at application runtime, not policy selection.
To avoid such a situation, you must not activate conflicting policies at the same time. Such policies are meant to be
enabled one at a time to optimize the system for ISV applications running in different modes. If you get a policy
conflict message, please disable one of the profiles.
System Maintenance
1. Why does “Check for Updates” or “Apply Updates” fail?
Check for updates or Apply updates may fail if you do not have an internet connection or if the Dell server is not
reachable. Please check your network connection and try again after some time.
