Entering License Key for QT Commercial SDK



  • Hey, I just got the 30-day trial of QT commercial with QT creator and tools.

    When I try to compile any project, I get this:

    *This software is using the trial version of the Qt GUI toolkit.
    The trial period has expired. If you need more time to
    evaluate Qt, or if you have any questions about Qt, contact us
    at: http://qt.digia.com/contact-us for pricing and purchasing information.

    Qt 4.8.3 Evaluation License
    Copyright (C) 2012 Digia Plc
    All rights reserved.

    This trial version may only be used for evaluation purposes
    Registered to:
    Licensee: "MY NAME"R&D

    The evaluation expires in -1 days

    Contact http://qt.digia.com/contact-us for pricing and purchasing information.*

    The problem is I had previously downloaded the wrong installation and enter my key there. How can I enter a new key or change the old one? It says I can change the key in the SDK Manager but that only lets me install/update/remove. I've been trying to get HelloWorld to run for about 5 hours now, I'm really getting frustrated..



  • Finally got it working! Had to delete .qt-license in my Roaming appdata folder and reinstall.

    If you submit your project somewhere, you should check, whether the trial version is the rightone. It is for playing a bit around befor bying a commercial version.

    If you submit your project somewhere, you should use the GPL or LGPL version instead, and not try to reenable the commercial one.



  • Hello, I had the same situation and I just changed the license via the Qt Enterprise Management Tool:

    1. select the "update" option: it prompts to enter user and password
    2. enter user and password that you have on this website: https://account.qt.io/login
    3. it will prompt you to select your license. In my case I could choose from the trial version and the license I just purchased

    Done deal!
