What is the workflow

What is the application doing?

Iu2019m guessing you have a windows service application and you're trying to launch a UI (ie the viewer control) from the application or print using the vieweru2019s printing functionality programmatically(?).

If this is a Windows Service running under the local system account, then follow the instructions in the error message. (ie, bring up the properties of the service, go to the logon tab and check the checkbox that says u201CAllow service to interact with desktopu201D. At least that should allow whatever popup is trying to come up display properly.
