Returned versions are always initialized to zero, even on failure. 

Function always returns S_OK, even on failure.
Copy the file to the temp directory if the file exists but isn't found
by GetFileVersionInfoSize.
If bVersion is FALSE, return the language and code page identifiers of
the file, not the system.
