Prevent 2 applications from runing at the same time?

[JayUSA]

Hello,

I'd like to prevent 2 applications from ever running at the same time. If one application is open, I want the other application to fail to open. And vice-versa.

Perhaps there a trick or a utility that will prevent a specified application from opening if a service from another specified application is running?

I'm interested in all your ideas, thanks!

Jay

In the old days of Windows 3.1 - WFW 3.11, certain nested batchfiles could accomplish this. I do not know if Powershell can do similar nested operations. I'm guessing the normal click this icon or click that icon is probably not going to work.
