Single player skirmishes
What does not
SecuROM, DirectX installation.
What was not tested
Internet and Network play.
Install corefonts (and possibly tahoma) for better fonts. Some focus problems exist during installation, so use a virtual desktop. Need to copy d3dx9_30.dll into /Windows/system32 directory manually (either use a site such as dllfiles.com or cabextract it from the 1st CD's /DirectX/Apr2006_d3dx9_x86.cab). Install no-cd to get around secuROM problems. Per recommendation on previous AppDB notes, used winedbg for installing patches. Update EaW to 1.5 before installing FoC (patch is included on 1st CD).
