As I know starting from Windows Vista, VERSIONINFO resource is treated a bit different than in Windows XP. It seems that now it requires some additional information about multi-languages and translations.

See this post:

This additional info must be added to the resource file for proper information presentation (tested on my machine and my regional configuration):

BLOCK "VarFileInfo"
BEGIN
VALUE "Translation", 0x0409, 1252
END

1. Because by default QMake generates resource files without this additional information, text of some fields in file details dialog is not visible under Windows Vista or Windows 7 (see image Screenshots.png)

2. File Version and Product Version fields are filled with values taken from different places. File Version is taken form definition "FILEVERSION" and Product Version is taken from BLOCK "StringFileInfo", VALUE "ProductVersion". So these versions can differ if user wants this. Besides Product Version field is allowed to have free text, so version can have not only numbers but also some text that is very useful! To reflect this, it would be nice in QMake project files additionally to variable "VERSION" have separate variable "PRODUCT_VERSION" that could have free text form.
