Licenses and Authorizations

The free version of QLab is a powerful audio playback environment and available at no cost. If you require advanced functionality licenses are available to unlock additional features.
Three basic licenses are available: Pro Audio, Pro Video, and Pro MIDI. In addition, the Pro Bundle license unlocks all features available from the three basic licenses.
Standard (non-expiring) QLab licenses must be both installed and authorized on your computer. Rental licenses need only to be installed; there is no authorization process for a rental license.
You may transfer a standard license from one computer to another by deauthorizing the first computer, and then installing and authorizing the license on the second computer.
These steps are described in detail below.

How to install a QLab License

When you purchase a QLab license, a license file is sent to the email address you provide during checkout. This license file (which has the file extension "QLab2License" or "QLab2LicenseXML") can be installed by double clicking on the file or dragging the file onto the QLab application icon.

How to authorize your QLab computer

Once your standard, non-expiring QLab license is installed you must authorize the computer to use that license. (Rental licenses do not need to be authorized.)
IMPORTANT: You have a grace period between when you install a QLab license and when you must authorize the computer. The features unlocked by your license will be fully functional during this grace period. However, the functionality is not permanently unlocked until you authorize the computer. If the grace period expires before you authorize the computer QLab will revert to the unlicensed state until it is authorized.

Online authorization

If your computer is connected to the Internet simply go to "QLab" → "Licenses and Authorizations" and click the "Authorize this License" button for the license you wish to authorize. Your computer is now fully unlocked and authorized for this license.

Offline authorization

If you use a computer that can not connect to the Internet you can still authorize it to use your QLab license.
Go to "QLab" → "Licenses and Authorizations" and click the "Export Offline Authorization Request..." button for the license you wish to authorize. QLab will prompt you for a location to save the offline Authorization Request.
The offline Authorization Request is a simple HTML file you can open with any browser. It contains instructions on how to use the request. Simply take this file to a network-connected computer and click on the link to download the authorization file for your offline computer. The authorization file will have the file extension "QLab2Authorization". Transfer this file back to your offline computer and click the "Import Offline Authorization..." button to authorize this license.

How to deauthorize your QLab computer

You must be connected to the Internet to deauthorize a license on your QLab computer. Go to "QLab" → "Licenses and Authorizations..." and press the "Deauthorize and Delete this License" button for the license you wish to remove. If you wish to reauthorize your computer for that license you must reinstall the original license and reathorize the computer.
