Installation error: could not find QmakeOutputInstallerKey

  • Hi all, I am trying to install Qt 5.11.1 on a Windows 10 machine. I had 2 errors earlier in the process, but hitting "retry" seemed to work. This one won't go away with "retry", however. The full text of the error is:

    Error during installation process (qt.qt5.1111.qtcharts.win32_msvc2015): Could not find the needed QmakeOutputInstallerKey(qt.qt5.1111.win32_msvc2015_qmakeoutput) value on the installer object. The ConsumeOutput operation on the valid qmake needs to be called first.

    Any ideas?

  • well, I have made some progress. I tried installing to a different path, and the installation finished with no errors. So I guess the problem may have been related to permissions.
