Oops. Sorry, didn't even recognized it was german. No you don't have to, there is only a minority who speaks german here/is native german speaker. I'll translate it:
Wine configuration:
First, get the d3dx9_27.dll (
http://www.dll-files.com/dllindex/dll-files.shtml?d3dx9_27) and copy it to home/[yourusername]/.wine/drive_c/windows/system32
Next, open your registry (type in console regedit).
Change in HKEY_LOCAL_MACHINE->Software->Microsoft->DirectX the version to the value of "4.09.00.0904" and InstalledVersion "0000000900000000" (in case it isn't there make new keys (REG_SZ-type)).
Installation of EaW:
Install EaW via setup.exe (wine will catch this automatically). Next thing is to copy the no CD/DVD crack over the original files (it's not possible for wine to catch those CD-validation-requests): Switch to "/home/[yourusername]/.wine/drive_c/Programme/LucasArts/Star\ Wars\ Empire\ at\ War/GameData/" and paste the cracked content in.
Last thing is:
"wine sweaw.exe"
Maybe this doesn't work. in this case try:
"WINEDEBUG=-all wine sweaw.exe -SAFEMODE"
