    I was going to work with Qt 5.6 beta with MVS2015. To have Qt 5.6 beta can I just update Qt 5.5? I clicked on update components in "Maintenancetool.exe" , is this the component I need?

      No, that's Qt Creator. It's the IDE.

      IIRC, the 5.6 beta installer is available through your Qt Account page

        If you mean through this link, the Qt5.5 should not be uninstalled first?

          There's also that link indeed. Since it's an offline installer, I don't remember whether it will overwrite the Qt folder or not

            Is the installation way different from Qt5.5? Why does Qt5.6 give this error, while I installed Qt5.5 in the same folder?

              Don't put Qt in a path with white spaces, that will save you much trouble.

                If you mean "program files'' it was the same folder I installed previous Qt5.5 and didnt give any message. By default Qt5.6 beta selects the C drive to install.

                  That's what I mean. Avoid white spaces it's the best thing to do on Windows.

                        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

                            My system is windows 7 64-bit, and I am going to run a C++ code using Qt with MCVS 2015.
                            Just to prevent from over or re-installation again, could you please tell me which one I need to install?

                              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.

                                      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
