No ... I have the Steam version, and these always differ from the disc
based releases in many ways. If I recall correctly, the first time one
start CoH on Steam, the first thing that happens is a proprietary EULA
pops up which you have to agree with before the actual 'first time start
installation process' begins ; once that finishes, the title itself starts...
...it very likely -is- the same *game* software, but the installers differ
considerably. In Steam, what I describe above happens by way of 'virtual
file systems' and online interactions ; the installer on the DVD is likely
trying to accomplish exactly the same DRM tasks, however, instead of using
a mounted virtual filesystem or online negotiations to obtain the needed
DRM keys, it's trying to obtain such from the disc media itself (which may
likely fail for a number of reasons)...
...looking over at WineHQ, it seems most people there report installing
and patching the disc release using Windows, and (I guess?) copy the data
There are threads related to this on the 'net from Windows users, which speak
to what I say above. One of the complaints Windows users have about the Steam
version of CoH is that every time you launch the thing, you have to logon. It's
true, does the same thing in CXG...however...if you have the DVD version and the
DRM can authenticate itself against that media, you don't have to logon to the
game network. *Some* (not nearly all) DVD releases of games can be registered
using Steam, but I have no idea if CoH is one of them...
Hope this explains things...
