    Nor sure if I should post in 'Tools' section or here 'Installation and Deployment' because it is not clear if Install&Deploy is about software crated with Qt or the Qt software intself - please feel free to move to the more appropriate section

    Starting with Qt 5.10.0 (Offline Installer) I can't debug due to following error

    Internal error: The extension C:\PROGRAMS\Qt\Qt5100\Tools\QtCreator\lib\qtcreatorcdbext64\qtcreatorcdbext.dll cannot be found.
    If you have updated Qt Creator via Maintenance Tool, you may need to rerun the Tool and select "Add or remove components" and then select the
    Qt > Tools > Qt Creator > Qt Creator CDB Debugger Support component.
    If you build Qt Creator from sources and want to use a CDB executable with another bitness than your Qt Creator build,
    you will need to build a separate CDB extension with the same bitness as the CDB you want to use.
    

    MSVC2017 64 bit
    When I check the above path - only C:\PROGRAMS\Qt\Qt5100\Tools\QtCreator\lib\ - exists but .\qtcreatorcdbext64\qtcreatorcdbext.dll is missing

    I'm usign Offline Installer, checksum matches, no errors during installation
    In Offline Installer 'Add or remove components' there's no such component - 'Qt > Tools > Qt Creator > Qt Creator CDB Debugger Support component'

    Is 'Qt Creator CDB Debugger Support component' included in Qt 5.10.0 Offline installer or not? If not - from where to download?

    IIRC ..in previous versions there was an option (a button in QtCreator settings) to rebuild certain debug plugins (IIRC it was the same plugin - anyway there's only one default debug plugin) ..maybe only for GDB

    P.S. as suggested created a bug report here
    https://bugreports.qt.io/browse/QTCREATORBUG-19462

      @ThatDud3 said in qtcreatorcdbext.dll cannot be found - Qt 5.10.0 (offline installer):

      I'm usign Offline Installer, checksum matches, no errors during installation
      In Offline Installer 'Add or remove components' there's no such component - 'Qt > Tools > Qt Creator > Qt Creator CDB Debugger Support component'

      I can't verify that by now, but I know in the online installer there is such a checkbox and this is something that was added recently (I don't remember why they changed that, I guess it's a licensing thing).

      So I think best would be to file a bugreport at bugreports.qt.io for that issue. You can add a link to that report here afterwards.

      Thanks.

      Qt has to stay free or it will die.
