Is it possible to run 2 ryzom.exe on the same pc ? (ie dualboxing or what its called)

I know there are several that run 2 games on 2 computers, but this isnt an option for me, so would be nice if i could run 2 games on the same computer!

Usually, I can get 2 of the same game to run on my PC by making a second shortcut and setting it to run as a different user. However, I can't seem to get this to work with Ryzom :(

I think you may encounter 'port confusion' - as far as I know, both copies of Ryzom will use the same TCP or UDP port to transfer data, and I assume this would cause problems routing network packets (two processes on the same machine, sending and receiving info on the same port).

2 copies of a non-networked game is plausible, I think 2 copies of a networked game (specifically one that uses the same port numbers for both copies) is probably not possible... could be wrong tho :)

My last mmorpg ran fine as long as I set up the second shortcut to run as a different user so it's definitely possible for an online game to be written in a way that supports this. It's probably just specific to the way Ryzom is written.

It used to be possible back in beta, but it's disabled since some time before release..

If game uses only client initiated TCP connections, there should be no problem with ports running 2 clients on same machine.

If server opens TCP connections back to client or sends UDP packets, then client must have an open port and listen to incoming TCP or UDP packets.

2 programs can't share same port on same machine without special code. Dynamic or configurable port selection is possible, but would result in problems with firewalls and would require special coding for port negotiation between client and server.

Ive run AO and WoW 2 copies on the same computer just fine, was just a matter of starting the .exe file twice.

When it try to start it a 2nd time with ryzom, nothing happens.
