Rainbow 6 installation problems

i have american computer
and i tried to install rainbow 6 in german
and it start installing and suddenly stop and say
app main
app excutable some thing like this what is this?

Rainbowsix is the greatest game I have ever played in my life. I was addicted to that game for 3 years. So long to it though...the multiplayer is dying and it isn't as fun anymore. I used to have some great times playing r6.

1- multiplayer is dying with Raven Shield only because Ubi decided to use a cd-key entry system to access the online game server. It sucks, indeed, and I hope that no other software makers do this, or we are all going to wait for seriously discounted games. Around where I am from, the $10-$20 (older- by a couple of months), section at the computer store is a very popular place for gamers.

2- German? the reason, probably, that installation is erroneous, is because you do not understand the German script that accompanies the installation process, in form of pop-up options, and menus. Maybe you should get a German dictionary. (-: :P
