问题
I have recently graduated to VS 2015. For reasons explained below, I want to avoid running the VC++ Redistributables installer. I am including the prescribed DLLs in my installer, for an "app local" installation:
MFC140.DLL
concrt140.dll
msvcp140.dll
vccorlib140.dll
vcruntime140.dll
mfc140u.dll
mfcm140u.dll
This seems to work. My app runs when installed thus on a "virgin" PC.
My question is, where do I find
msvcr140.dll?
It is mentioned here: https://www.visualstudio.com/license-terms/mt228262/. I cannot find it anywhere when searching all directories on a PC where VC Redistributables has been installed. Does it exist? Is Windows concealing it?
Note 1: Why I need to avoid the MS VC++ Redistributables installer:
- It shows up as a separate install in my WiX installer. It is very confusing for my market demographic (consumers).
- When my software is uninstalled, it is also necessary to uninstall VC Redist., which can lead to complications.
- In a couple of instances, there has been some sort of screw-up that has rendered the PC inoperable. I suspect repeated VC Redist installs. What happens is that a Standard User is no longer able to start any programs.
- VC Redist. has bloated my installer from 25MB to 40MB, an extra 15MB. By picking which components I need, I trimmed it by 10 MB.
- WiX code to test for prior versions is complex, arcane and inscrutable.
- Yes, I understand about the benefits of automatic updating of Windows DLLs. However, a PC with out-of-date DLLs is better than a PC that is unusable.
Note 2: I can't do a static link, my app is a mixed bag of Win32 and MFC DLLs, I get linker errors.
回答1:
It appears that the "msvcr140.dll" is "missing" because of the introduction of the Universal CRT in Visual Studio 2015.
