I have a windows compatible text/speech program and I want to see if I can run two of these programs at once on my Windows XP computer.
I downloaded a second copy and can open each one up seperately, but not at the same time. When open & running the program runs in the system tray.
Any thoughts on how I might accomplish running them both at the same time?

If I partioned the disk and installed on seperate disk would that do it?
I look forward to any suggestions.
Thanks.

I don't think you can.

If they don't launch at the same time, it's most probably because those programs where designed not to, and if they detect themselves already running, they exits silently.

Or, maybe it's like firefox, which application is only a launcher, and exists when a process run.
If you try to re-launch it, it will only open a new window, and not a second instance.

Installing on a separate partition won't change a thing. This is nothing related to the file system.

Like tripy said, if the app is only allow to be running one session at a time, you won't be able to. If you want to get around it, you can try installing VMWare, run one session of your text-to-speech program on the host computer and than anothe session in the VMWare session. Let us know how that turn out

On a server would setting up two different seetings in Microsoft IIS do it? Or two different IP addresses?

IIS is a web server. You usually only have one process at a time.
And a IP address is just an "specification" of your server.

No, when we say that you can't, we mean it.
Or you have a meaning of isolating the process in memory to prevent them to detect themselves.

The simplest way would be to run a virtualisation solution (like vmWare, or virtual pc) but I don't see any solution except that one.

thank you
