Hello, I am exactly in the same situation, I specify that I own the two original games in French.
When launching edain mod here is error message:
Error: 64 bit and 32 bit registry strings of the game found. Updating the modmight not work correctly
And during the update:
_edain_data.big not found. The update might bot work correctly in this case
____edain_maps.big not found ....
__edain_german.big not found ...
__edain_textures1.big ...
__edain_textures2.big ...
__edain_terrain.big ...
_edain_music.big ...
__edain_w3d.big ...
__edain_apt.big ...
widescreen big ...
_____english_ini.big ...
_____voice_english ...
German patch 201...
English patch 201...

German.big
I also specify that the two games (bfme 2, bfme 2 rotwk) are installed in their original folder
Thanks for finding a solution to this problem and thank you for this wonderful mod
