qDebug() etc. has stopped appearing in my application output

[kenchan]

it seems to be related to these errors...
mincore\com\oleaut32\dispatch\ups.cpp(2122)\OLEAUT32.dll!00007FFE460B9DD6: (caller: 00007FFE460B91E9) ReturnHr(1) tid(28a4) 8002801D Library not registered.

Exception at 0x7ffe44314f69, code: 0xe06d7363: C++ exception, flags=0x1 (execution cannot be continued) (first chance) in UIAutomationCore!wil::details::ThrowResultExceptionInternal

Does anyone know anything about this?
How can i fix it?

The output works when i run it without the debugger??

I will be very grateful for any suggestions to fix it.

Thanks,
kmj.

@kenchan I assume that you've not forgotten to include #include<qDebug> headerfile as well as a message input for qDebug().

[kenchan]

it was working until that error started showing up.

@kenchan
I don't know what you can do about it (I have only glanced, you need to investigate), but there are references to this:

• https://bugreports.qt.io/browse/QTBUG-63789

• https://stackoverflow.com/questions/44579720/qt-widget-application-library-not-registered-error

and others maybe from Google qt 8002801D Library not registered.

I suggest you look through those....

@JonB
thanks for the links.
the bug report is good clue. as for the others "been there, done that" and not made any head way.

cheers,
