Theoretically it's possible. But you may need to have some rather intensive CPU's as one instance of the application uses 100% of the CPU process and eats up the RAM, so you may need two or more Gig of RAM.
First you'd need to set your application to run in Windowed mode. You do this by entering into the game itself.
- Open up Options -- Menu / Options
- Click Graphics and Audio tab
- Set Screen/UI Resolution to Windowed
- Click Save and Close Window
- Quit the game -- /quit
Now, you should be able to open two instances of the program ... should. I was able to do this on a laptop using two Gigs of RAm, but the second instance was sooooo slow loading and seemed like it was taking FOREVER because of the amount of CPU utilization being shared between the two processes. The CPU fan was working overtime, to say the least.
Eventually, I had to kill the process with Task Manager because the CPU was working way overtime and I couldn't get anything else to run and was unable to switch processes to already-running applications.
It might work better on a dual-core, or dual-processor design with two to four Gigs of RAM. But hey, I'm no expert at these things.
That's why I said "theoretically".
Your best bet is to run two computers, side-by-side. But it's not possible to open the same account on two separate processes, or two separate computers.
