The second one unless you are planning to use WinRT

I dont have any idea about that, I was just running a C++ code in Qt and get outputs in UI... how can I know if it was installed before in Qt5.5? Moreover, there is a "_64" difference between the two: qt-opensource-windows-x86-msvc2015_64-5.6.0-beta.exe 17-Dec-2015 and
qt-opensource-windows-x86-msvc2015-5.6.0-beta.exe -
The _64 is to be used if you want to build a 64 bit version of your application. That also requires a 64 bit OS to run.
The Beta doesn't installed itself in 5.5 since it's the 5.6 beta

If you plan to only run your application on 64bit Windows, then take the 64bit version otherwise the 32.

I installed the first one here to be able to run my projects using MCVS 2015 compiler. It worked last week. I think I have still the older Qt 5.5. and couldn't uninstall it.
Now I am again trying to run my project, but cannot find the Qt5.6 beta. when I open the Qt shortcut on my desktop, it has only the MCVS 2013 as compiler.
How can I run projects using Qt 5.6 beta shown here and get rid of Qt 5.5?
In addition, when I open the "MaintenanceTool.exe" to update it, this error appears. -
Qt 5 beta should be installed somewhere like C:\Qt\5.6.0. In any case you are probably using the Qt 5.5 installed Qt Creator. Either add a Qt Version and a Kit in the Preferences of Qt Creator using your Qt 5.6 beta or start the Qt Creator from Qt 5.6 beta.
If you don't what that mix, just remove both and re-install only Qt 5.6 beta.
There's nothing to update in a beta version.

Yes, Qt 5.6 beta is in C:\Qt\5.6.0. This is my Qt5.6 beta that I sent in previous post. But may I ask how to start the Qt Creator from Qt 5.6 beta?
Could you please let me know how to "add a Qt Version and a Kit in the Preferences of Qt Creator using Qt 5.6 beta "?I was going to uninstall Qt 5.5. before installing Qt 5.6. beta, but it gave this error asked in one of my previous posts.

Like written on the dialog, don't install Qt in "Program Files", the spaces always poses problems.
Then use the Qt Creator from Qt 5.6 so you don't have to configure anything special, it should already have it auto-detected.

The Qt 5.6 beta was installed in C:\Qt\5.6.0, not program file.
Qt 5.5 was previously installed in program files, but it worked properly. When I open Qt 5.6., this folders appear, I dont know where the Qt Creator from Qt 5.6 is.
When I open the Qt creator on desktop, it only shows this compiler, not "Desktop Qt 6.5. MSVC 2015".
I am wondering last week, I could run it immediately after I installed Qt5.6. beta. -
QtCreator should be in C:\Qt\5.6.0\Tools
You can create a Kit with the right compiler and Qt version in QtCreator under Tools/Options/Build & Run -

If it is there you should find it.
But here is the path: C:\Qt\5.6.0\Tools\QtCreator\bin\qtcreator.exe -

You mean you want to have a short-cut on the desktop? Drag and drop qtcreator.exe to the desktop using right mouse button and then select "Create shortcuts here"

First thing: don't use cout since it will send the text to the console.
You can simply put a QLabel with hello world as text as central widget of your MainWindow class.

Previously I tried a simple project to print out "Hello world" in one of my previous posts. The C++ code was written in MSVC 2013 gives output. Here is one of my previous posts related to getting output of C++ code written in MCVS 2013 in Qt5.5.
Here is my previous post:
"The above output was the debug using "Desktop Qt 5.5.1 MSVC2013 64 bit". I didnt debug with MinGW. The problem is the way I use to get the results in UI.
I tried a simple project to print out "Hello world", the C++ code written in MSVC gives output. Could you please take a look at my files:
Here are the content of C++ all files.
main.cpp
Bucky9.cpp
stdafx.cpp
targetver.h
stdafx.h
Now I created a Qt widget project, and I added the C++ code stdafx.h, targetver.h, and stdfx.cpp files using "Add existing Files" to the header and source. I didnt add Bucky9.cpp and main.cpp. Instead, I coppied the main.cpp C++ codes in the Qt main.cpp file with a little changes of all files.
(Changes: 1- Bucky9 is not included in Qt.
2- In stdafx.h #include <char.h> instead of <tchar.h>
3- Including #include "stdafx.h" in mainwindow.cpp.Here are the content of all files in Qt project:
main.cpp
mainwindow.cpp
stdafx.cpp
stdafx.h
targetver.h
mainwindow.h"I could get "Hello worlds" with QLabel using Qt5.5 and MCVS 2013. The only difference is that I didnt change <tchar.h> in stdafx.h. Now, when I run it, it builds it, but the run button is not active. Here is the code: Qt code
Is there any change when I am working with MCVS 2015 and Qt 5.6 beta? Some of my Qt 5.5. works, but some of them dont work. -
What is the content of your *.pro file?
