A patch was created by community member Bibber to fix the issue, which also requires all individual games from The Ultimate Collection to have the Origin In-Game option manually disabled. The Ultimate Collection writes certain registry files incorrectly, causing connection issues with users of other versions of the individual games and inability to run mods or command line parameters. The pre- Tiberium Wars games within The Ultimate Collection were likely ported from the obsolete 1.01 patch of The First Decade compilation.
