dlltie.dll is not part of Windows, it would have been installed by the game.
Sometimes games will install a .dll file in System 32, but often they install it to the games main install folder or a sub-folder in the install folder.
In the case, according to the post below, the file is supposed to be in the games install folder.
See if this helps -
"DllTie.dll is located in the same directory that Dark Crusade is installed in
("C:\Program Files\THQ\DarkCrusade").
But the Dark Crusade shortcut that the installation program created in the start menu is
missing the "Start in:" directory.
Just add the directory to the shortcut and everything will work."
You could also try making a new shortcut directly from the games executable
file ( .exe ) in it's install folder.
