I have seen cases where the installer wants to do an Update of Visual Studio 2017 before allowing you to do the Modify action. Clicking on the Modify button will bring up the installer to allow you to modify the various components. I then looked for Microsoft Visual Studio 2017 in the list of apps, clicked on that entry which then displayed the Modify button. In Windows 10 with Visual Studio 2017 Community Edition to modify the Visual Studio 2017 installation, I had to go into Settings from the Windows Start menu then in the search box enter 'Apps & Features' to bring up the list of installed applications (just typing in 'apps' was enough to bring it up in the list). I don't think there's any entry in the installer to do this at all-but if you try to build a project that uses narrow-character MFC, you'll get an error message that includes a link to download it.

If you want the narrow-character version, you have to install that separately.

That's not necessarily the end of the story though: by default, even when you install that, it only installs the version Unicode build of MFC. There are versions for ARM, ARM64, and x86/圆4 both with and without Spectre mitigations, for each of the 141 and 142 build sets: In the VS 2019 installer, the list of possibilities has gotten even longer. In there, you'll find a list of components for ATL and MFC support: To get it, you first have to click on 'Individual Components', then scroll quite a ways down to get to the 'SDKs, libraries and frameworks' section. If you look near the top of the VS Installer window, you'll see Workloads, Individual Components and Language Packs.Īt least as far as I can see, none of the 'Workloads' will include MFC in your installation.
