How to know when and exe is done running

[Technocrat]

I am making a program that runs an .exe program to update an another program. I am using shell to run the .exe update and I need to know when it is done running so I can continue. The program that updates does not show up on the task bar but does show up in the task manager. What can I use to know when the update is complete?

Thanks
