QuarkXPress Emergency License File (.qxpelf) Functionality

Background -The .qxpelf is created has an invisible file in the QuarkXPress/QuarkCopyDesk folder when the supported application launches and connects to the QLA Server for the first time. The Emergency License file is locked to the Ethernet card/NIC/Mac Address of the machine on which it was created. Any change to the Mac address of the machine will cause the .qxpelf to become damaged. The .qxpelf file will also become invalid if you try to change your system time either forward or backward by more than a few minutes.

In addition, you will receive a damaged .qxpelf error if you allow it to expire. In this case you can make it visible and delete it from QXP folder, along with the XPress Preferences file, which records the current amount of time the .qxpelf file has been used. The .qxpelf file will be regenerated the next time QuarkXPress connects to the QLA Server successfully.

The remaining number of hours of the Emergency Key always displays when QuarkXPress or QuarkCopyDesk launch. No expiration warnings display while working in an application running on an Emergency Key.


In Quark License Administrator (QLA), there are three backup systems put into the technology to allow your users to work should the QLA Primary Server go down. These are, in order:

  1. The QLA Backup Server: This full functionality license server runs redundantly in the background and pings the QLA Primary Server on a regular basis to ensure that it hasn’t failed. If it detects that the Primary Server has failed, it will begin to serve all supported software licenses until it detects the Primary Server is back up and running.
  2. The Emergency License File for the QLA Server: This is a visible QLALicense.dat file that is e-mailed to you when you download your QLALicense.dat file. The Emergency License File is used when your Primary Server machine suffers a catastrophic failure and you need to put up a new machine with an identical IP address to support your users while you fix the Primary Server computer. The Emergency License file will allow you to run this substitute server and support your QuarkXPress/QuarkCopyDesk licenses for up to 5 days.
  3. The QuarkXPress Emergency License File (ELF) is an invisible file that is stored in the root level of the QuarkXPress folder. This local Emergency License is designed to allow QuarkXPress to launch using the local .qxpelf file in the event your site experiences a catastrophic network failure. It will allow a QLA–supported application to run for up to 120 hours before it expires. While in use, the ELF will count down the number of hours in use.

This article specifically covers functionality of the local QuarkXPress Emergency License File (.qxpelf).
