I have produced an exe from a C++ program using Visual Studio Community 2019. I gave the exe to a friend to run on his PC (he is not a programmer and does not have Visual Studio installed). When he ran my exe he got an error report that vcruntime140.dll was not found. I then had a vague recollection that I have had this issue giving my exe's to other people before and I seem to remember that I could do something at my end (a link option?) that completely avoided the need for the end user to have the dll on their system. Unfortunately I can not remember exactly what I needed to do.
EDIT: I see this question has been marked as a duplicate - I can see the logic behind this. The other question is closely related and the marked solution and will indeed sort out this problem. But I don't want to delete this question because my user reported a missing vcruntime140.dll not MSVCP140.dll. If someone is troubled by a missing vcruntime140.dll they would never find the "duplicate" question.
