I checked with strace:

openat(AT_FDCWD, 
"/usr/lib/wine/../x86_64-linux-gnu/wine/dpinst64.exe.so", O_RDONLY) = -1 
ENOENT (No such file or directory)
write(2, "0009:err:module:__wine_process_i"..., 
850009:err:module:__wine_process_init 
L"C:\\windows\\system32\\dpinst64.exe" not found
) = 85

copied the lib:
sudo cp programs/dpinst64/dpinst64.exe.so 
/usr/lib/x86_64-linux-gnu/wine/

now I am getting:

$ wine64 ~/.wine/drive_c/windows/system32/dpinst64.exe
002b:err:module:__wine_process_init 
L"C:\\windows\\system32\\dpinst64.exe" not supported on this system

The same with setup.exe:

$ WINEDLLOVERRIDES=dpinst64.exe=b,n WINEDEBUG=dpinst+trace wine64 
Setup.EXE
0032:fixme:shell:SHChangeNotify ignoring unsupported flags: 2001
