how do I detect an instance of setup already running?

[dave2000]

Is there a way to detect if the same setup is already running? I'd like to prevent users from running the same setup twice (at the same time).

Why u need to do that? If u run the setup twice concurrently, the second launch will fail.

Perfect answer !!

If you have some other requirement, then you have to use the API to know if another instance of the program is running.

For some reason, the second time I run the same setup it doesn't detect itself and fail.

Is there an api call I can use to check this?
