Do you get this when using the "file open save" (Speichern als..) dialog only?
Do you see this also with other programs e.g. notepad or whatever?

The dialog you are using should be the standard, native "file open save" of windows.

What system OS are you using?
What tool chain is this?

[Fuel]

The first Message i get always, but the others i get with my QFileDialog. By the Way the Dialog is very slow at the Moment, but it works. I use Windows 10.

@Fuel

Did you get the recent update to "Windows creative" as they call it?
Possibly an incompatibilty in there.

Where do you see these error messages?

[Fuel]

Dont know. I see the Errormessages in my QT Creater in the Output Window. The Program works fine, but i dont like the messages.

I get the same error regarding OLEAUT32.DLL not registered. But everything works anyway. Do you have any idea what might be wrong?

@Fuel , @vlada
Just to be clear: it is not uncommon for Windows internals (which is what you are seeing here) to generate "Unknown error"s etc. during it's normal operation. Because you are using Qt Creator to run you will see these in the Output Windows, but they don't appear to the end-user at runtime. Other debuggers (e.g. Visual Studio) will also show such errors in its windows, nothing to do with Qt. So these may be harmless, unavoidable messages.
