Concerning the "fixed Info":
PRODUCTVERSION and FILEVERSION are set from [AssemblyInformationalVersion] and [AssemblyFileVersion] respectively.
FILEOS, FILETYPE are most likely set by the compiler.
Concerning the Var File Info
[AssemblyCulture] maps to "Translation" (I guess!)
Concerning the String File Info
[AssemblyCompany] maps to "CompanyName"
[AssemblyDescription] maps to "Comments"
[AssemblyFileVersion] maps to "FileVersion"
[AssemblyTitle] maps to "FileDescription"
[AssemblyInformationalVersion] maps to "ProductVersion"
[AssemblyProduct] maps to "ProductName"
[AssemblyCopyright] maps to "LegalCopyright"
I think "InternalName" and "OriginalFile" are set to the name of the DLL or EXE, respectively.
