I’m trying to compile and run my executable for both Debug and Release modes for testing. However I’ve encountered an issue of a missing dll for msvcp140d_app.dll and msvcp140_app.dll for debug and release modes respectively.

I’m using Visual Studios 2017 on Windows 10 using x64.

I’ve checked the WindowsApps folder and can only find the non _app versions. 
I’ve also downloaded the installed packages from C++ Runtime v14 framework package for Desktop Bridge (Project Centennial)
which provided the msvcp140_app.dll but no debug version.

Also sorry if this isn’t the correct tag and please point me to the correct forums for this problem.

Hi friend,

Welcome to MSDN forum.

What type of project you use? Simple C++ console app or QT project?

And it could be better If you share more details about the entire error message so that we can help you check it or direct it to correct forum.

Thank you for your understanding and cooperation. We are looking forward to your reply!

Best Regards

Lance

Hi Lance,

Its a actually a OpenGL application generated from a CMake file. I have found a work around solution for the missing .dll.

I copied msvcp140d.dll' from the vs2017 install directory, placed it into my project folder and renamed itmsvcp140d_app.dll’. 

Currently it works. So I believe this renaming is done by a third party distribution of those dlls renamed.
