问题
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.
回答1:
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.
