    Hi,
    I opend the Maintenance Tool and added QT 5.15.2 to the existing 5.15.0. When I tried to add the new version (5.15.2) to Visual Studio, it complained "Error: Qt license file was not found!". The same error appears when running qmake.exe.
    It meant to be an open source license, at least it always was so far.
    Any ideas? Thanks.

      Martin is one of the DeepSkyStacker team so his post is strictly related.

        Did you get any error messages, or messages about licenses, during the installation of Qt 5.15.2?

        Also, if you open Qt Creator, are you able to build a basic "Hello World" program?

        When I tried to add the new version (5.15.2) to Visual Studio, it complained "Error: Qt license file was not found!". The same error appears when running qmake.exe.

        Did you change Windows account between installing Qt 5.15.2 and running Visual Studio?

          No error messages during installation of 5.15.2.
          Never made a QT program before, so I'm not familiar with QT Creator. I'll try it later.
          I did not change the Windows account, in fact I ran Visual Studio immediately after installation of QT.

          Wouldn't it be best to completely uninstall QT (every version) and then make a fresh installation of 5.15.2?

            While working to port the open source project DeepSkyStacker to Qt from MFC I've been using 5.15.2. The other contributors to the project haven't been doing very much with Qt in the early stages of the work, but now we need to get all of us using the same version of Qt (free version of 5.15.2 ideally)

            Trouble is, where can they download it from? The automatic installer is only offering 6.4 and we don't want to switch to that until we've completed our port to 5.15.2 (or a later version of 5.15)

            Can you assist with this please?

            did you check LTS Archive ?

            since a couple of updates ago, Qt5 is no longer in the latest supported releases. Their "subtle" way to push developers to use Qt6.

              The online installer definitely offered me 5.15.2

                Still unsolved (though it may be moot as I made changes for 6.4.0 earlier today.

                  @Perdrix again, did you check the checkbox "Archive" and pressed the "Filter" button?

                  My online installer then shows me all Qt Versions, including 5.15.2 to download.

                    It's Martin's problem with lack of a license that's not solved

                      This means you have installed the commercial packages, but don't have a valid license currently.

                      Switching between commercial and open source installations is not that straightforward. You need to completely uninstall Qt on the machine, and then start fresh.

                      In the installer, please check if it says 'Welcome to Qt commercial setup.", or "Welcome to Qt open source setup" right after giving your Qt Account credentials.

                        This is a screenshot of the Qt maintenance tool. It says "Open Source License".
                        Even though it obviously installed a commercial version of 5.15.2.

                          @mtoeltsch It could be that your commercial license has expired, so the installer only shows open source options.

                            I never had a commercial license. I just had Qt 5.15.0 installed 08/2020 as open source.
                            And now I wanted to add Qt 5.15.2.
                            That's it.

                                What happens if you run the "update components" option (second on that screen)?

                                  Alright, that's weird then . Do you have a licheck.exe executable in %QTDIR%\bin (so for instance C:\5.15.2\msvc2019_64\bin\licheck.exe)?

                                      I currently have numerous versions of Qt on my machine (installed from my open-source account). Qt 5.12.11, 5.12.12, 5.15.2, and 6.0.0 all come with licheck.exe but Qt 6.2.4 and 6.4.0 don't.

                                      Yes, this is worth a shot.

                                      1. Completely uninstall everything related to Qt (including Qt VS Tools)
                                      2. Delete your account/license *.ini files in C:\Users\%USERNAME%\AppData\Roaming\Qt\
                                      3. Reboot for good luck
                                      4. Run the online installer again and install Qt 5.15.2 fresh.

                                      After that, open Qt Creator and load an Example project (say, the "Analog Clock Example"). Click the "Run" button to build and run it (it's quite a straightforward process). This will help to verify that you can use Qt.

                                      And after that, re-install Qt VS Tools from the Visual Studio Marketplace and try to add your Qt 5.15.2 again. Does it work now?

                                        @JKSH said in Qt 15.5.2 download:

                                        I currently have numerous versions of Qt on my machine (installed from my open-source account). Qt 5.12.11, 5.12.12, 5.15.2, and 6.0.0 all come with licheck.exe but Qt 6.2.4 and 6.4.0 don't.

                                        Your right. I now double checked, and it seems licheck.exe is part also of the Qt 5 open source packages. The differentiation for qmake actually happens in mkspecs/qconfig.pri (QT_EDITION, QT_LICHECK).

                                        So, if a Qt installed via an open-source installer asks for a license, the patching of these fields most likely failed. Does InstallationLog.txt show any errors?

                                          In the meanwhile we upgraded to Qt 6.4.0.
                                          So I uninstalled everything from Qt und made a fresh 6.4.0 installation. It works now.
                                          Thanks for your help.
