Hello again,

well it's late so ... ;-)

VerInstallFile() flags -> VIFF_DONTDELETEOLD

MSDN says for VIFF_DONTDELETEOLD: "Installs the file without deleting the
previously installed file, if the previously installed file is not in the
destination directory."

The source and destination file are binary identical.
Maybe VerInstallFile() isn't supposed to delete the destination in this case?
Another method might be overwriting the destination file (instead of
delete/move), keeping the original long file name.
