License check failed under Qt5 but not Qt6

[dknx.8888]

Hello! I just got an Educational license for Qt, and when I installed Qt Creator with Qt5, the license check is failed when opening projects. This is not the case for Qt6, as projects opened without any issues. I have an application that only supports Qt5 for development, so I cannot use Qt6. Thank you if anyone can help me out!

Hi @dknx-8888
You will need to talk to The Qt Company to resolve issues with non-open source licenses.

@dknx-8888 Maybe the license is only valid for Qt6? You should clarify this with Qt Company like @ChrisW67 wrote.

Hi @dknx-8888 , you should be able to create a ticket for Qt support in the customer portal (login to your Qt Account). -> Support Center
