I'm attempting to install Qt 5.11.2 and Qt creator through the .run installer found on their website.
I can get through the installer just fine, but when the installer finishes downloading and starts installing to my filesystem it always hangs at the exact same point.
Specifically, when its writing /Qt5.11.2/Src/qtwebengine portions. However I don't believe this is the issue because even if I uncheck the box for web engine before installing it still crashes at a specific point somewhere else. Ubuntu gives me the option to force close every time, I have waited to make sure it doesn't come back but it never does.
Can anyone offer any help? I'm not sure if maybe i'm missing some dependencies the installer needs or there's just something wrong with Qt's installer?
Thanks.
I just needed to let it sit for 20 minutes.

I downloaded C++ code from GitHub to tag images for training an object detector using Machine Learning.
Within Qt Creator 4.2.1 Based on Qt 5.8.0 (MSVC 2015, 32bit), I was able to compile and run the code. Unfortunately, I was not able to run the .exe outside of Qt Creator.
Initially, I received an error that
"The program can't start because libgcc_s_dw2-1.dll is missing".
Thanks to
QT The program can't start because libgcc_s_dw2-1.dll is missing, that was fixed easily by adding
"QMAKE_LFLAGS += -static"
to the .pro file. Now, when I run it I get
"The application was unable to start correctly (0xc000007b). Click OK to close the application."
I was able to reproduce the error using the simple "Hello World" default project that appears when you create a Qt Widget Application. This led me to believe something was wrong with my installation.
Based on the advice of this article: https://stackoverflow.com/questions/12099117/32-bit-qt-application-on-win-7-x64-wont-run-but-runs-fine-from-qt-creator, I used Dependency Walker to identify possible causes. I expected to see only a few items that I can follow up on. Instead, I received a list of close to 100 missing .dll files. All the files started with
"API-MS-WIN ###.DLL" or "EXT-MS ###.DLL"
where ### represent some additional text characters, for example;
"API-MS-WIN-SHCORE-STREAM-WINRT-L1-1-0.DLL"
I'm attaching a sample output.
Another suggestion was to copy over
libwinpthread-1.dll, libstdc++-6.dll, libgcc_s_dw2-1.dll.
That did not work either.
My next move was to simply get the latest version of QT and wish for the best. I installed Qt Creator 4.8.1 Based on At 5.12.0 (MSVC 2015, 32 bit). This time, I could not even get the code to run in the IDE. I received 1000+ error messages!
Based on advice from several pages, I added
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
to the .pro file and it still would not compile.
Also, I verified that the application is being built as a 32bit application. I'm running on a 64 bit Windows 10 system.
If anyone would like to take a crack at it to see if they can create a working .exe, here is the link: github.com/clavicule/BBTag
Qt provides a tool to copy the necessary dlls to the folder of your executable.
The tools is called windeployqt.exe and comes with your Qt installation. For me it is located at C:\Qt\5.9.1\msvc2015_64\bin\windeployqt.exe. You will have to look at your installation path and probably the msvc_32 folder to find it.
Then you go to the folder with your executable in it, oben a command prompt or powershell and execute path\to\windeployqt.exe yourProgram.exe and it will automatically copy the necessary dll files to this folder. Afterwards you can run your program without issues.
The official documentation for the tool can be found here.
Alternative 1: While developing you could use QtCreator which automatically adds the paths to the dlls when running your program - make sure to include them if you deploy your program!
Alternative 2: Add the path to the necessary dlls to your PATH variable. This isn't recommended either, since everyone who gets your program would have to do the same to run it.
I figured it out! My installation of Anaconda (a Python distribution popular for data science and machine learning) is the culprit.
From: #remy-lebeau
The application was unable to start correctly (0xc000007b)
The error:
"The application was unable to start correctly (0xc000007b) ..."
is a good indicator that the 32-bit app tried to load a 64-bit DLL. At first, this did not make sense since I verified many times that I was using the 32 bit version of Qt.
It turns out that the installation of the 64 bit version of Anaconda also contained many Qt5 dlls used for the PyQt5 package. Since the path to this folder came before the path to my c:\Qt...\bin folder, it was used in the build instead of the actual 32 bit version installed with Qt. This was not obvious because I was unaware of PyQt5 so I had no idea that it came with Anaconda. A simple reordering of the path entries using the System Environment Variables interface AND a system restart fixed the problem.
Silver lining: I now know C++ and designing GUIs w/ QT and PyQt5

I installed several times the qt creator but it never cost me as much as in my current PC; First I used the installer that always had on my Pendrive (that of Qt 5.8), told me that I could not download some repositories, I downloaded version 5.9 of the same installer, with the same result. After trying to install it several times and it did not load I went to another house where I managed to install it, although I had to be very aware of many errors coming out of missing libraries (while installing Qt 5.9). After this I had to download the sp1 for my win7 OS through "windows updates" to run the Qt creator, but later, when loading, creating or running a project, I would say in console (it does not matter if it is GUI) the following : "Could not determine which" make "command to run. Check the" make "step in the build configuration." I would very much appreciate your help to anyone who wants to advise me, because I have already had many problems with my computer, from losing everything (the previous hard drive had installed original win10) to a series of very annoying setbacks like this. I cannot post images, I have no more than 10 reputations.

The problem is that the video you posted is for linux, but i thank you for your help. I need now more he
You have to set a valid compiler to build your project. As any compiler is not set, it is asking you to check the configuration.
For example in my PC, I get the following as compiler output:
11:13:33: Running steps for project ListViewExample...
11:13:33: Configuration unchanged, skipping qmake step.
11:13:33: Starting: "C:\Qt\Qt5.2.1\Tools\mingw48_32\bin\mingw32-make.exe"
C:/Qt/Qt5.2.1/Tools/mingw48_32/bin/mingw32-make -f Makefile.Debug
Here you can observe that C:/Qt/Qt5.2.1/Tools/mingw48_32/bin/mingw32-make is the make compiler which builds the application.
You can set the compiler path here:
Tools > Options > Build & Run > Kits. Select the kit displayed and select a
valid compiler.

I've just recently started out with Qt and created a simple Qt Widgets application. When I build and run the application (even if I make a fresh project with no new code in it) I get the following error messages:
mincore\com\oleaut32\dispatch\ups.cpp(2128)\OLEAUT32.dll!74445072: (caller: 7444FE4F) ReturnHr(1) tid(188) 8002801D Library not registered.

My Qt install and Windows are both up to date. I've been searching for a solution for a couple hours now and I can't find anything even remotely relevant to the problem online... Has anyone else anywhere had a similar issue?
Update:
I just completely removed Qt from my PC and did a fresh install and I am still getting the same messages.
Ugh. This problem wrecked my sunday.
I'm on QT 5.9.1, Windows 10, Surface Book.
I tried reinstalling windows, didn't work. I tried reinstalling Microsoft Runtime, didn't work. Reinstalled QT in a million different ways, didn't work.
So I was on the latest updates, and checked my oleaut32.dll version - 1.1.15063.0. According to an old forum post I found around, this error can be caused by the application requesting a newer version of oleaut32.dll than you have. So I jumped onto the insider preview versions (picking the slow ring) and was upgraded to release 10.0.16251 which also upgraded my oleaut32.dll. Fixed it, no error anymore. QT creator finally works.
I guess QT requires you to be on beta windows now?
I've looked for an answer during a few days and I haven't found anything similar anywhere;
I downloaded Qt from the official website, installed it and apparently compiling is fine. But whenever I try to execute (Ctrl+R) any app, even the basic one which only displays a window or widget, QtCreator itself crashes. No error message, nothing, just crashing.
I've tried to redownload and reinstall it a few times with different settings, but nothing will do.
I'm running QtCreator on Windows 7 64 bits. I'll try on my laptop which is also running windows and will update if I find anything.
Any help would be appreciated, I need to start a project as soon as possible. I'm relatively new to QT and if you need info on anything just ask me. Thanks :)
Use dependency walker, http://www.dependencywalker.com/
and post any missing dependencies. It is possible some install targets or options are missing from when you installed QtCreator, which can be resolved with the maintenance tool in the same directory you installed Qt.
Also, are you using the Visual Studio compiler(must have Visual Studio installed separately, and mark the option during install), or the Ming compiler(2 options checked during install or maintenance)?
Check if your antivirus is locking it, I had a similar issue time ago and it was due to antivirus (Avast specifically). Disable antivirus' realtime shields and try to execute a basic app.
It is necessary to use QtCreator? I use QtDesigner snd VS2013 and things go very well. :)
check this thread Qt Creator Plain C++ Project won't run/debug... and this C++ - QtCreator doesn't show any output
I have a really weird problem here.
I am using Qt 5.5.0 with mingw 4.9.2 32bit and QtCreator and Git on Windows 7.
My Project builds just fine but when I run the executable either outside or inside QtCreator the process appears in Task-Manager/ProcessExplorer but the Window itself does not show up and when I try to kill the process it does not react. Process Hacker can't terminate the process either. The QtCreator debugger waits in vain for the process to start. I have to reboot the PC to kill the process.
Thing is that it worked a few days ago and other qt projects work fine, too. I had the same issue on a different PC. I couldn't find the issue so I reset it to stock; I can't do the same with this one.
What could I have possibly done to cause this?
OK, I found the issue. It was my antivirus software. I am using avast free antivirus and somehow it caused the issue without telling me. Excluding the build directory from the scans solved the issue.
Thanks to Paul for the answer!
