I have developed a GUI with QT and my release version needs vcruntime140_app.dll to run. I couldn't find this dll in my SysWOW64 folder, so I reinstalled the Microsoft Visual Stuio C++ 2017 Redistributables which (according to Microsoft) contain the vcruntime140_app.dll. The _app dlls are still not there after the reinstallation. The same dlls without _app are all there.
The vcruntime140_app. dll File is a DLL (Dynamic Link Library) System File provided by Microsoft for Windows 7, Windows 8, Windows 10, and earlier Versions. These . dll Files contain various instructions that different pieces of software may need in order to run properly.
On the menu bar, choose File > New > Project to open the New Project dialog box. In the left pane of the New Project dialog box, select Installed > Visual C++ > Windows Desktop. In the center pane, select Dynamic-Link Library (DLL).
The Visual C++ Redistributable installs Microsoft C and C++ (MSVC) runtime libraries. These libraries are required by many applications built by using Microsoft C and C++ tools.
The Microsoft Visual C++ installation error might be caused by corrupted registry keys. In this case, the Microsoft Program Install and Uninstall troubleshooter could resolve the issue. The Microsoft Program Install and Uninstall Troubleshooter will scan and repair corrupted registry keys.
I had the same error and found out that I used the wrong dll.
In my case I developed a desktop application but used the binaries in "winrt_...", where I should have used the binaries in "msvcXXX.." instead.
As I understand winrt is for developing windows store app.
Hope this helps.
