How to package vcruntime140.dll for a wix custom action DLL written by native c++?

Question

My wix wxs has a CustomAction written by c++: HSRInstall.dll. Inside this dll, windows swdevice.lib, new.lib are linked. So it requires running with vcruntime140.dll. When user execute this msi package on a clean install windows server 2019 datacenter, without a vcruntime140.dll in C:\Windows\System32, it will fail to be installed.

<Binary Id="HSRInstalldll" SourceFile="HSRInstall.dll" />
<CustomAction Id="deletehsrservicecache" BinaryKey="HSRInstalldll" DllEntry="HSRCustomAction" Execute="deferred" Impersonate="no" Return="ignore" />

When I add vcruntime140.dll as binary element in wxs, its file name is changed when installing. How to add the vcruntime library that the dynamic library depends on to the wix package? Thanks!

The best option is to statically link the C runtime (CRT) into your custom action dll. That way you do not have a dependency outside of your installation package.

We statically link the CRT in all the WiX custom actions.

My custom action is a dll developed by QT 5.15.2, I try to set CONFIG -= qt && MAKE_CFLAGS_RELEASE += /MT && QMAKE_CXXFLAGS_RELEASE += /MT in the pro file. But nothing happens. – Acewind Feb 13 '23 at 10:07
Sorry, I'm not a QT developer. – Rob Mensching Feb 13 '23 at 13:05
