I have some bunch of Qt-based softwares (such us VLC, Calibre, Krita, Mendeley Desktop, MalwareByte, Free Download Manager) which run in the background but not show any GUI in a Windows 10 machine. All related qt*.dll are available in their respective folders. I did tried to install/uninstall, but the problem persists.

But, I have other Qt-based softwares are running well (Octave, Anaconda).

I think the problem is related with the GUI setting of either Octave or Anaconda.

Any ideas?

Hi, a colleague had some strange problems in the past that were caused by programs that modified some of the PATH variables.
You could check with Dependency Walker (http://www.dependencywalker.com/) if the programs really load the Qt DLLs from their own directory.
