Windows 7: An Instance is already running

An Instance is already running

Hi all, first post here new member good forum. That said I am running win 7 pro 64. I have an application named freightmaster on my machine which has multiple users on it. Lets say there are 5 users. It was all running fine for some time.

Now on 3 out of 5 users the application just runs in memory when launched and pins to the taskbar, when I try to open it from there I get "An instance of freightmaster is already running, please close this down before starting a new session.
Facts are ... I do not have any other instances running on any other user as I have them all logged out when I launch it. The icon is from the public desktop and it is only run by clicking the icon. I watch in taskmanager and yes a second instance of the application does run in mem when when I try to maximise the first instance from the taskbar, although it never "fully opened" in the first place.

Anyone had this sort of thing ?

Thanks heaps ozzie

This might help, press CTRL+SHIFT+ESC. This opens Taskmanager, click the processes tab, look through the list for anything that resembels the name. Right click it and choose end process tree.

Then run the program normally as you would.

Note: Just make sure there is a user name next to it in the list and not SYSTEM, LOCAL SERVICE or NETWORK SERVICE, just a username. Oh and untick the check-box to only show your processes.

Hello and Welcome to SevenForums.

Maybe the program you're trying to run doesn't work on your current O.S.

Have you tried to execute this on Windows XP and run successfuly? If the answer is YES, then that's the answer.

That is for Seaman's program I pressume?

It has been and is running on 3 out of 5 users, Yes Luckystar I can end the instance when it runs but it (ends the instance) It's like the app runs but doesn't get access to the console or something. I'm leaning towards this idea because the application does in fact run on some users profiles on the machine. Freightmaster simply prints lables for our dispatch.
