Qt VS Tools: error reading VS project settings - c++

I develop an application using Visual Studio 2015 + Qt VS Tools extension. For me it's first time I used Qt (version 5.14.1) in my project. Everything was working fine until something wrong happened.
I was asked to make release version of my application, it worked fine on Windows 10 and Windows 7 64-bit systems. Then I set the project configuration back to Debug x64 to continue my work. First strange thing I noticed - when I double-clicked on *.ui form files in my Solution Explorer, Visual Studio crashed and reloaded without any error, Qt Designer doesn't launch.
What I tried:
First I tried to open Qt Designer externally (from bin folder in Qt directory) and open my form - it worked.
I tried another project made in VS 2015 + Qt VS Tools Extension - same problem.
I tried to remove my Qt Version and re-add it. And here it comes: Error screenshot. It also occurs without using system enviroment variable $(QTDIR).
I reinstalled Qt to my PC (installed version 5.14.2 instead of 5.14.1), same error.
I reinstalled Visual Studio 2015, same error.
I tried to reset my Visual Studio settings and parameters to default, no results.
I installed Visual Studio 2019. The problem is still present.
UPD:
I cleared Visual Studio cache according to these instructions. It didn't work for me.
I removed every Visual C++ Redistributables from my PC and installed the latest version from Microsoft site. It also didn't work.
The error occurs even if no project is opened, so the problem is caused either by Visual Studio 2015, by Qt 5.14, or by Qt VS Tools extension.
P.S. Sorry if my english wasn't perfect. Waiting for any ideas on fixing this problem.

For any future readers who have this problem, start your maintenance tool or Qt installer, e.g. C:\Qt\MaintenanceTool.exe, "Add or remove components", and then make sure Qt/<version>/MSVC is installed, as shown in the image below:
.
Then you'll be able to select that Qt version instead of MinGW, since the Visual Studio extension only supports the MSVC compiler and not MinGW.

Encountered the exact same problem and the only solution I have found was reverting to an older version of the Qt Visual Studio Tools extension.
Visual Studio has been painfully persistent about updating the version even once I installed an older one, so make sure to disable automatic extension updates (Extensions → Manage Extensions → Extension Settings → Uncheck Automatically search for updates/Automatically update extensions).
Hope it helps.

To solve your problem, you need to remove the QTDIR and QMAKESPEC environment variables that remain in Windows after installing older versions of Qt.

Well, after some more procedures that didn't help, I just did clean-reinstallation for my Windows 10. Fortunately, that helped :)

Visual Studio 2013, error MSB8020: The build tools for Visual Studio 2010 cannot be found

At the start I'd like to note that I've spent some time researching this issue and suggested solutions for similar questions like this one didn't help me.
Problem background
I need to migrate a Firebreath plugin project (which I haven't worked on previously) from PC_1 to PC_2.
As far as I'm aware the project was started on PC_1 on Visual Studio 2010 and later moved to Visual Studio 2013 Pro. There's one solution consisting of 19 projects. I have an instruction which says that in order to get the plugin installer I should first Build project_x and after that Build project_y_WiXInstall. Both steps work without any issues on this machine.
Then there's PC_2 which had Visual Studio 2015 Community installed before I started working on it. I've removed it, installed Visual Studio 2013 Pro (version 12.0.21005.1 REL - exactly the same as on PC_1), moved all of the needed files and I'm trying to get rid of all of the compilation errors. So far I figured out I had to install Cmake 2.8, Windows Driver Toolkit 7.1 and manually override an incorrect VCTargetsPath MSBuild variable
Problem description
Currently when I try to compile the project on the new machine I get these two errors (this is an image link since I can't embed images yet on this account). I'm not sure what's going on with the first error message since it looks incomplete and the file CUSTOMBUILD doesn't exist, but I'm not bothered by it too much since the previous compilation error I fixed also had a similar "artifact" as the first error and it disappeared after fixing the second one.
The covered part of the second error message is the project path. The error origin (Microsoft.Cpp.Platform.targets file, line 64) looks like this:
<!-- Error out if toolset does not exists in Visual Studio 2010 or 2012 -->
<VCMessage Code="MSB8020" Type="Error" Arguments="$(_CurrentPlatformToolsetShortName);$(PlatformToolset)" Condition="'$(ToolsetTargetsFound)' != 'true'" />
What didn't help
The error description suggests using an Upgrade Solution... option, but there's no such thing when I right-click the solution
As an accepted answer for the question I've posted at the start of my post suggests, I've checked the Properties of all 19 of my projects (including the project ZERO_CHECK) but their Platform Toolset is already set to Visual Studio 2013 (v120).
I've also tried changing the Platform Toolset to inherit from parent or project defaults for all of the projects. This resulted in it switching to Visual Studio 2010 (v100) (not installed) and after that I've right-clicked on the projects and chose Upgrade VC++ compiler and libraries. After this the Platform Toolset was back to the Visual Studio 2013 (v120) but it didn't help with the compilation error.
As a NON-accepted answer for the question I've posted at the start of my post suggests, I've tried searching for all of the occurrences of 10.0 and V100 in all of my .vcxproj files to replace them but I haven't found any occurrences of them.
[EDIT]
I just got an idea to try building the project with MSBuild from the command line. There's a bit more info compared to errors inside Visual Studio, so maybe it will help with resolving the issue: https://pastebin.com/JhN3dXM3
So the thing you're missing here is that FireBreath projects are built using CMake -- the actual contents of the build directory should always be completely temporary and never stored in source control. To build the project on a new computer you need to run the prep command again from scratch.
If the previous maintainer changed the build files manually and/or migrated it to a newer version of visual studio without using cmake to do it then they did some very ugly things and all bets are off... good luck.
This is why all the firebreath documentation (I wrote most of it) strongly urges that the build directory be transient and you always do project file updates in cmake.
Hope that helps!

How to fix the error "Windows SDK version 8.1" was not found?

I recently updated visual studio 2015 and now, when i try to build any project it always fails and i get the error
Severity Code Description Project File Line Suppression State
Error MSB8036 The Windows SDK version 8.1 was not found. Install the required version of Windows SDK or change the SDK version in the
project property pages or by right-clicking the solution and selecting
"Retarget solution". Proj D:\Program Files (x86)\visual studio
2017\Common7\IDE\VC\VCTargets\Platforms\Win32\PlatformToolsets\v141\Toolset.targets 34
I retargeted the solution as it said, and the problem persisted, even though the retargetting was completed.I decided to install visual studio 2017 because of this, and, lo and behold, it did the exact same thing.I'm also using windows 7.
What is the problem and how can i fix it?
I faced this problem too. Re-ran the Visual Studio 2017 Installer, go to 'Individual Components' and select Windows 8.1 SDK. Go back to to the project > Right click and Re-target to match the SDK required as shown below:
I installed the 8.1 SDK's version:
https://developer.microsoft.com/en-us/windows/downloads/sdk-archive
It used 1GB (a little more) in the installation.
Update October, 9 (2020). There's a https error: the sdksetup link is https://go.microsoft.com/fwlink/p/?LinkId=323507
"Save link as" should help.
Another way (worked for 2015) is open "Install/remove programs" (Apps & features), find Visual Studio, select Modify. In opened window, press Modify, check
Languages -> Visual C++ -> Common tools for Visual C++
Windows and web development -> Tools for universal windows apps -> Tools (1.4.1)
and Windows 10 SDK ([version])
Windows and web development -> Tools for universal windows apps -> Windows 10 SDK ([version])
and install. Then right click on solution -> Re-target and it will compile
I had win10 SDK and I only had to do retarget and then I stopped getting this error. The idea was that the project needs to upgrade its target Windows SDK.
I realize this post is a few years old, but I just wanted to extend this to anyone still struggling through this issue.
The company I work for still uses VS2015 so in turn I still use VS2015. I recently started working on a RPC application using C++ and found the need to download the Win32 Templates. Like many others I was having this "SDK 8.1 was not found" issue. i took the following corrective actions with no luck.
I found the SDK through Micrsoft at the following link
https://developer.microsoft.com/en-us/windows/downloads/sdk-archive/ as referenced
above and downloaded it.
I located my VS2015 install in Apps & Features and ran the repair.
I completely uninstalled my VS2015 and reinstalled it.
I attempted to manually point my console app "Executable" and "Include" directories to the C:\Program Files (x86)\Microsoft SDKs\Windows Kits\8.1 and C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools.
None of the attempts above corrected the issue for me...
I then found this article on social MSDN https://social.msdn.microsoft.com/Forums/office/en-US/5287c51b-46d0-4a79-baad-ddde36af4885/visual-studio-cant-find-windows-81-sdk-when-trying-to-build-vs2015?forum=visualstudiogeneral
Finally what resolved the issue for me was:
Uninstalling and reinstalling VS2015.
Locating my installed "Windows Software Development Kit for Windows 8.1" and running the repair.
Checked my "C:\Program Files (x86)\Microsoft SDKs\Windows Kits\8.1" to verify the "DesignTime" folder was in fact there.
Opened VS created a Win32 Console application and comiled with no errors or issues
I hope this saves anyone else from almost 3 full days of frustration and loss of productivity.
Grep the folder tree's *.vcxproj files. Replace <WindowsTargetPlatformVersion>8.1</WindowsTargetPlatformVersion> with <WindowsTargetPlatformVersion>10.0</WindowsTargetPlatformVersion> or whatever SDK version you get when you update one of the projects.
For me in the Project Properties Settings General->Target Platform -> Change Windows 8.1 to Windows 10 solved the issue
Install the required version of Windows SDK or change the SDK version
in the project property pages
or
by right-clicking the solution and selecting "Retarget solution"
If you do visual studio guide, you will resolve the problem.
I encountered this issue while trying to build an npm project. It was failing to install a node-sass package and this was the error it was printing. I solved it by setting my npm proxy correctly so that it could reach the npm repo
PROBLEM: I ONLY get this compile-time "Windows SDK version 8.1 not found" error ( and a few other very-hard-to-resolve-nuisance errors -- cannot list them all ) when I export a project from an old version of MS Visual Studio (VS) to the new MS VS (2017), using the new MS VS export/"One-way Upgrade" feature.
SOLUTION: I have since learned to not use this export/upgrade feature and instead just create the new project from scratch -- using all my old source files, of course. Only my project settings have to be rebuilt, to be clear.
This is a bit of a pain, and a shame the export/upgrade feature won't work properly like it used to, but this is is actually easier and faster in the long run. MUCH better than working through a list of spurious errors that really should not have arisen in the first place.
Hope this helps...

"LNK1104 Cannot open file 'kernel32.lib' " when Windows SDK version is set to 15063.13

I'm doing C++ in Visual Studio 2017, and just recently updated Windows 10 from Anniversary Update to Creator's Update.
I found out by accident that when I'm compiling a DLL project, I would get the error message:
LNK1104 - cannot open file 'kernel32.lib'
After twiddling a bit in the Project Properties, I noticed if the Windows SDK version is set from 10.0.14393.0 to 10.0.15063.0, the error message appears. If I set it back to 10.0.14393.0, I can compile just fine.
I would like to know why when the Windows SDK version is set to the Creator's Update build version, it's throwing this error message, yet it doesn't if set back to the Anniversary Update's build version?
Thanks.

The Windows 10 Creators Update SDK made some significant changes to
what is installed as part of the installation to minimize on-disk
footprint. This is a Known Issue that results from that refactoring
work where the "desktop" components of the Creators Update SDK do not
get installed by default. The previous new project logic always
selected the latest Windows 10 SDK, assuming the desktop portions were
installed as part of that installation scenario. We are working on a
fix for a future update.
The workarounds available are as follows:
Select a version of the Windows 10 SDK that's fully installed on the system (i.e. 10.0.14393.0 or earlier) in the Project Properties
Install the 'Windows 10 SDK (10.0.15063.0) for Desktop' component via the Visual Studio Installer. win10sdk-15063desktop.png

I have the same problem, honestly, looks like a bug in VS 2017. Just switch to 10.0.10586.0.

Visual Studio doesn't recognize Unreal Engine

I'm a student in Videogame Development, and just starting out looking at Unreal.
And no, none of my teachers know anything about this.
I have installed Unreal Engine 4.13 and Visual Studio Community 2013 now 2015.
I'm trying to make a C++ project using Unreal Engine (using blueprints is out of question so this didn't help)
Now, when I make a basic C++ project, Visual Studio shows the following error message:
Unsupported
This version of Visual Studio is unable to open the following projects. The project types may not be installed or this version of Visual Studio may not support them.
For more information on enabling these project types or otherwise migrating your assets, please see the details in the "Migration Report" displayed after clicking OK.
- UE4, "C:\Users\Gebruiker\MEGA\Unreal\Disposable\Intermediate\ProjectFiles\UE4.vcxproj"
- Disposable, "C:\Users\Gebruiker\MEGA\Unreal\Disposable\Intermediate\ProjectFiles\Disposable.vcxproj"
No changes required
These projects can be opened in Visual Studio 2015, Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1 without changing them.
- Engine, "Engine"
- Games, "Games"
- Disposable, "C:\Users\Gebruiker\MEGA\Unreal\Disposable\Disposable.sln"
Then my browser opens showing a Migration Report telling me that VS had an error with Project.vcxproj and UE4.vcxproj, although it copes with Engine, Games and Project.sln.
After this VS does show up without any further action, and it does automatically open *.h and *.cpp files for newly added classes in UE4.
Though it does edit and save these, it claims that all UE's code is wrong (with squiggles), and for compiling UE4 gives errors on pieces of code that apparently don't give errors on other's machines.
It would be much appreciated to be helped out, and I'm sure it would help others too who would have the same problem.
EDIT
A screenshot of the problem and configuration
EDIT 2
A screenshot of the Help -> About Visual Studio page, VS 2015 C++ highlighted
Starting with both the Unreal Engine Editor and Visual Studio closed, right click your .uproject file and select Generate Visual Studio project files, and then launch visual studio from the .sln file.
Once Visual Studio is open check your Solution Configuration is set to Development Editor. Then go to Debug > Start without Debugging (or Ctrl-F5). If everything compiles and the Editor opens again then you're good to go.
I uninstalled VS2013, installed VS2015 with all additional options checked, made a blank, new project with Unreal with just VS2015 on my pc, and now everything works fine.
Perhaps my VS2013 installation was broken, deprecated or switching version wasn't a good idea, but I can work with VS in any case now.
Also thanks to jeevcat for mentioning it!
Install newer version of the Visual Studio. VS2013 is not the latest one, VS2015 is. People report that even updating VS2013 from Update 2 to Update 4 helps resolving similar issues.

Qt <codecvt> : No such file directory

I cant use std::wstring_convert in Qt 5.1, because it said me that <codecvt> : No such file directory. What can I do? I don't know... this code is working at the MSVC 2013.
QtCreator is just a front-end that allows you to edit your source files, it does not contain a compiler. On Windows you need either MinGW or Visual Studio to compile code.
If you want to use Qt 5.1 with Visual Studio 2013, you would have to compile Qt yourself. Digia provides builds for Visual Studio 2010 and 2012. You can find the latest version of Qt here or an old release here.
My advice would be to install Visual Studio 2012 and download a VS2012 build of Qt. Then go to Tools > Options > Build & Run > Kits, click the Add button on the right (or modify the existing one as it probably won't work anyway). Set the compiler to "Microsoft Visual C++ compiler 11.0 (amd64)" if you downloaded the 64 bit version of Qt or "(x86)" if you downloaded the 32 bit version.
Then set the debugger to cdb.exe and the Qt version to the one you just downloaded (if you don't see it, go to the Qt Versions tab at the top, add it, click Apply and the go back to Kits and it should be there). Click ok and your kit should be ready! Make sure that you don't have a warning signal that would point out a potential mistake.
Now open your project and go to the Projects tab (Ctrl + 5) and make sure your project is using the correct Kit.
You should now be all set up properly.
Additionally, if you don't want to install Visual Studio 2012 and want (or have to) work with VS 2013, you can use the Qt 5.3 BETA builds located here. Please note that these builds are in beta and shouldn't be used in production code, if you want to use VS2013 with Qt in production code I would recommend to build Qt 5.2.1 with VS2013, it's not that hard but it can take a while.
You are missing this in your project file:
CONFIG += c++11
You need to make sure that your GCC version (brought to you by mingw) supports that feature though. It is possible that you are using an old version where it was not supported.
