Releasing a licence
The computer's calibration and QA history is saved to a ZIP archive and emailed to your Customer Admins, then removed from your web account. The ViziCAL app on that computer stops reporting, and its displays are no longer calibrated.
You can also release a licence from the computer itself. See Licensing.
History archives¶
History archives lists the calibration and QA history of each computer whose licence was released. Click Download ZIP to download one. It can show Preparing… for a short time after the licence is released.
