Hello, complete newby here, I am using QT, version 5.9.1 for Windows. I installed it with the standard settings. Then I created a "Plain C++ application" with the "Desktop Qt 5.9.1 MSVC2015 64bit" Kit (the only available one), which then creates a simple main.cpp: #include <iostream> using namespace std; int main() { cout << "Hello World!" << endl; return 0; } When I then press Ctrl+R, a console window opens, but it only says, I should press Return to close the window, no Hello World. In the output panel in QT I read: Starting C:\Users\user\QTProjects\build-plainConsole-Desktop_Qt_5_9_1_MSVC2015_64bit-Debug\debug\plainConsole.exe... C:\Users\user\QTProjects\build-plainConsole-Desktop_Qt_5_9_1_MSVC2015_64bit-Debug\debug\plainConsole.exe exited with code -1073741515 Which, as I already found out, implies, that some library is missing. Shouldn't QT have configured the necessary dependencies? What am I missing? I already read here in the forum that some paths have to be added in the PATH environment variable. I do wonder, why the installer of QT did not add those, but anyway. I added the two bin paths, which I found in the Qt installation folder to the PATH environment variable, but it didn't change the outcome: C:\Qt\5.9.1\msvc2015_64\bin C:\Qt\5.9.1\winrt_x64_msvc2017\bin I am confused that not even the default project is running on its own after a plain Qt installation.

Hi, ok, so this took some time. Yesterday I found, that I had installed a mess of Microsoft and Windows SDKs and I thought, let's clean this up. So I uninstalled all those SDKs. Then I read the Qt documentation again and it says, that I should install a compiler as a requirement for Qt. One of the recommendations is to use Visual C++ build tools. So I have installed the Visual C++ Build Tools 2015. Then I start Qt, but I cannot compile my plain c++ app in Debug mode, because Qt cannot find a debugger. After some investigation, I find, that the Visual C++ build tools 2015 do not contain a debugger. Why isn't that mentioned in the documentation? So after somer further googling I find, that the Windows SDK comes with a debugger (the cdb.exe). So I install the Windows SDK. Now I have a debugger. Then, when I tried compile my app in debug mode, I got this error: LINK : fatal error LNK1158: cannot run 'rc.exe' So, for some reason, the place, where the rc.exe is, wasn't in my PATH. Added it, now finally , I can compile both the debug and the release version and run them without errors. Man, I have to say, I haven't even written one line of code as of now, but I am already exhausted. Thanks for all the help, though. Much appreciated.

@ ghost23 Close, but no cigar. Error "0xc000007b" means that your 64-bit console program is trying to load the 32-bit version of ucrtbased.dll :-( You need to find a 64-bit flavor of ucrtbased.dll on your computer.

@ghost23 "I cannot compile my plain c++ app in Debug mode" - you don't need a debugger to build in debug mode. You only need it if you want to debug.

"Why isn't that mentioned in the documentation?" - it is: http://doc.qt.io/qtcreator/creator-debugger-engines.html
