Don't know where to start but here I go:
The official download page doesn't have patch 2.100 to 2.101. It jumps from 2.100 to 2.103. But you can grab it from sites like "worthplaying" (I just check that
)
The only one there is from 1.701 to 2.101 but it's only for the vanilla CoH. Can't be applied into CoH:OF.
Since the OP never talked after the inital post (only god knows why) we can only make assumptions here.
Even with a warez copy he can patch. Afaik, in GCW you have a crack til patch 2.301 and in the instructions it says to apply the official patch over a full installation (of course you must install a serial of patches: 2.100->2.103, 2.103->2.201, ..., 2.300->2.301) but it will be patched.
However, he may has a wrong version or it's already patched and he doesn't know.
We'll never know if he doesn't talk.
One thing I laugh at was the "I want to patch COHOF for more balanced gameplay". LOL!
The patches in strategic games comes from feedback in multiplayer not in campaign unlesss you have a serious problem. I had a hard time to get some medals after patched the game long time ago in vanilla CoH. To get those medals I'd reinstalled the game and play it without a patch and get the medals easier.
The patches for any CoH games are intent for multiplayer not singleplayer.
Anyway.. he can buy the game through steam (e.g.) @ 15€ or in some shop as retail for similar price.
