    Greetings,

    I set up an Open Source version of Qt and then accidentally downloaded the licensed version of Qt (I was looking to get the examples and didn't realize they came with the open-source version of Qt). My system is no longer building and telling me that my license has expired.

    How would one revert my qt listen to open source?

    Your help would be very much appreciated.
