'Comments' part of VERSIONINFO not displayed

Question

I'm trying to use 'Comment' field of VERSIONINFO resource. The target program is 64-bit windows EXE file (compiled with VS 2015).

All elements like version, copyright, description and so on are shown correctly - except "Comments". I define it just like other elements of StringFileInfo block. Something like that:

VS_VERSION_INFO VERSIONINFO
FILEVERSION     FILEVER
PRODUCTVERSION  PRODUCTVER

FILEFLAGSMASK   VS_FFI_FILEFLAGSMASK
#ifdef _DEBUG
FILEFLAGS VS_FF_DEBUG
#else
FILEFLAGS 0x0L
#endif

FILEOS          VOS__WINDOWS32
FILETYPE        VFT_APP
BEGIN
   BLOCK "StringFileInfo"
   BEGIN
      BLOCK "000004b0"
      BEGIN
         VALUE "FileDescription",  PROGRAM_NAME
         VALUE "LegalCopyright",   COPYRIGHT_NOTE 
         VALUE "CompanyName",      "My Company\0"
         VALUE "FileVersion",      STRFILEVER
         VALUE "ProductName",      STRPRODUCTNAME
         VALUE "ProductVersion",   STRPRODUCTVER
         VALUE "InternalName",     "program\0"
         VALUE "OriginalFilename", "program.exe\0"
         VALUE "Comments",         "A comment to show\0"
      END
   END
   BLOCK "VarFileInfo"
   BEGIN
     VALUE "Translation", 0x0000, 0x04b0
   END
END

When I display version info with PowerShell, like this:

 (dir *.exe).VersionInfo|fl

empty "Comments" are displayed.

I also sigcheck program from SysInternals:

sigcheck -a .\program.exe

It displays:

...
Comments:       n/a
...

"N/A" ? Does it mean I need to set some special flags, or something to get Comments shown?

Answer 1

To make it work I had to add /D _UNICODE /D UNICODE to resource compiler command line:

rc.exe /D _UNICODE /D UNICODE ....

With such command line - Comments are there! Looks strange to me that it is required only for Comments, while other predefined fields do not require it. Anyway - thank you guys for hint - I had a look how VS does it.
