Except at least on Windows, if you have rights to execute the program, finding out what an application is creating is a matter of running a debugtool. The app doesn't need debugsymbols for that.
So this scheme would only work if 2 mutexes were used:
The app would then:
1)generate a new name and create a new mutex
2)try to open a mutex with the previous name stored in an encrypted file and if succeeds store this name, if not terminate.

other ideas that I used in practise
1)instead of displaying an error message, you can also bump the running instance.
2)instead of terminating, close the running instance by sending a signal to it, wait for it to terminate, if it doesn't terminate on time, forcefully kill it. Then proceed starting the app.
