Hi, @Bevan Thomas •
I tested wix project including merge module
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Redist\MSVC\v143\MergeModules\Microsoft_VC143_CRT_x64.msm
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Redist\MSVC\v143\MergeModules\Microsoft_VC143_MFC_x64.msm
And I am able to find mfc140u.dll and vcruntime140_1.dll in system32 folder.
What you need to check
1.Is your exe 64-bit?
You can manually copy the 64-bit output files to the test machine to see if the problem still occurs.
2.Are there mfc140u.dll and vcruntime140_1.dll files in system32 folder?
Best regards,
Minxin Yu
