If you attempt to launch another instance of TE, you'll' get a message to indicate that another instance is already running (same applies to TC). I've never tried, but I'm sure it's possible to run TC and TE at the same time. However, I see no reasons to do this. Also, if you're running TE and modifying the scripts at the same time, you'll be fighting to gain control of the mouse cursor, if doing UI testing. And, not sure why you would want two different users at the same time.
If you can explain exactly what you are trying to do, then may be we can suggest alternative solutions.
Thank you, RRaghvani,
As I mentioned to Marsha, it is my fault that I didn't mentioned about the fact that each instance of TE or TC will be installed on different user on the same virtual machine.
The advantage of this setup, I guess, is that customer will pay the license for a single OS, and allocate to this a single machine.
The reason of several users connected at the same time, is to give each user the option to run its own suite tests.
TC instance will be useful, if a user need to modify its scripts, not necessarily the scripts running with TE.
