Kelly, i think they are all optional
Like the mods in TWOS parts in SH5.
Furthermore the one with (Rus) may be only in Russian...
You should be able to play only the parts installed.
Except of course if you want the translation so the English font fix is required, and a wide screen mod.
I still can’t launch any career, except the naval academy.
All is installed in my C drive outside program files or program, even without the ARB wide screen mod it is CTD...launching with or without Commander.
