Programmatically get the ProductVersion of .exe using GetFileVersionInfo API (C++)

Referencing to this answer I'm trying to get ProductVersion with windows Api using GetFileVersionInfo method. The problem is that through the propreties of .exe ProductVersion is visible, but programmatically I get only "0.0.0.0".

.exe propreties:

exe propreties

output:

output:

Code:

                printf( "File Version 1: %d.%d.%d.%d\n",
                    ( verInfo->dwFileVersionMS >> 16 ) & 0xffff,
                    ( verInfo->dwFileVersionMS >>  0 ) & 0xffff,
                    ( verInfo->dwFileVersionLS >> 16 ) & 0xffff,
                    ( verInfo->dwFileVersionLS >>  0 ) & 0xffff
                    );

                printf( "File Version 2: %d.%d.%d.%d\n",
                    ( verInfo->dwFileVersionLS >> 24 ) & 0xff,
                    ( verInfo->dwFileVersionLS >> 16 ) & 0xff,
                    ( verInfo->dwFileVersionLS >>  8 ) & 0xff,
                    ( verInfo->dwFileVersionLS >>  0 ) & 0xff
                    );


                printf( "Product Version 1: %d.%d.%d.%d\n",
                    ( verInfo->dwProductVersionLS >> 24 ) & 0xff,
                    ( verInfo->dwProductVersionLS >> 16 ) & 0xff,
                    ( verInfo->dwProductVersionLS >>  8 ) & 0xff,
                    ( verInfo->dwProductVersionLS >>  0 ) & 0xff
                    );

                printf( "Product Version 2: %d.%d.%d.%d\n",
                    (verInfo->dwProductVersionMS >> 16) & 0xffff,
                    (verInfo->dwProductVersionMS >>  0) & 0xffff,
                    (verInfo->dwProductVersionLS >> 16) & 0xffff,
                    (verInfo->dwProductVersionLS >>  0) & 0xffff
                    );

                printf( "Product Version 3: %d.%d.%d.%d\n",
                    (verInfo->dwProductVersionMS >> 16) & 0xffff,
                    (verInfo->dwProductVersionMS >>  8) & 0xffff,
                    (verInfo->dwProductVersionLS >> 16) & 0xffff,
                    (verInfo->dwProductVersionLS >>  8) & 0xffff
                    );

The question is - WTF? How to get ProductVersion, and how do the guys from Microsoft did that?

this worked on my end

   fwprintf(f_output, L"// File Version:\t\t\t%d.%d.%d.%d\n",
        (verInfo->dwFileVersionMS >> 16) & 0xffff,
        (verInfo->dwFileVersionMS >> 0) & 0xffff,
        (verInfo->dwFileVersionLS >> 16) & 0xffff,
        (verInfo->dwFileVersionLS >> 0) & 0xffff
    );
    fwprintf(f_output, L"// Product Version:\t\t\t%d.%d.%d.%d\n",
        (verInfo->dwProductVersionMS >> 16) & 0xffff,
        (verInfo->dwProductVersionMS >> 0) & 0xffff,
        (verInfo->dwProductVersionLS >> 16) & 0xffff,
        (verInfo->dwProductVersionLS >> 0) & 0xffff
    );

Here is the code snippet for those who also trying to get the ProductVersion:

if (!VerQueryValue (lpData, TEXT("\\StringFileInfo\\040904E4\\ProductVersion"),
        (LPVOID) &lpBuffer, (PUINT) &BufLen)) {
    /* language ID 040904E4: U.S. English, char set = Windows, Multilingual */
    printf ("ProductVersion:       not found\n");
}
else
    printf ("ProductVersion:       %s\n", lpBuffer);

Here is Full Code.

The version info resource contains a small fixed portion (VS_FIXEDFILEINFO) and optionally some strings.

Some applications display the numbers from the fixed portion and some use the FileVersion/ProductVersion strings.

You should probably use the string if it is present because it allows the developer to add extra pieces of information like Alpha/Beta etc. and because some people forget to properly set the correct version in the fixed part.

Use the VerQueryValue function to get a list of languages and the strings...
