KB235352863: FlexoPerfection - Fails to start with the error "The application cannot start; No valid dongle found"

Summary

When you try to start FlexoPerfection version 10 or 12 using network licenses, it fails with error message:

"The application cannot start; No valid dongle found"

Symptoms

FlexoPerfection 10 or 12 is installed on a (new?) workstation, the required FlexoPerfection 10 network licenses are on a license server.

Possibly other Esko applications (Editors) installed on the workstation work fine using the license server licenses.

When trying to start FlexoPerfection, an error message "The application cannot start; No valid dongle found" pops up:

Solution

In the Environment Variables (This PC > Properties > Advanced System Settings > Environment Variables... > System Variables), change the value of the variable LM_LICENSE_FILE from "@localhost" to "@hostnameofthelicenseserver":

Reason:

The Esko Editors have a setting in their Preferences to define the license server (by its hostname), FlexoPerfection does not have this, so it needs to be set in the LM_LICENSE_FILE variable (which defines the default license server for Esko applications).
