ProppFrexx ONAIR User-Forum

Hello,
I have the Enterprise 4.4.1.5 version on Windows 10 Pro.
I am not yet on air.
Very often, when I run ProppFrexx I get a pop up alert that says: "ProppFrexx ONAIR already running
There is already an instance of ProppFrexx ONAIR running on this machine!" Etc.
Has anyone ever had this problem and knows how to solve it?
Thanks to all,
Claude.

Close the ‘other’ existing and running instance. See the task manager for details.
By default you can only start one instance on a PC - except you allow it explicitly via a command-line option (see the user manual for details).

Hi Bernd, thank you for your reply.
When I see this alert, if I look at the task manager, I only have one instance, the one that is starting up. That's why I don't understand this alert.

There must be another instance running on the PC, as ProppFrexx does the same, it looks to the list of running processes to determine, if another instance is running.
Maybe by another user?

You were right, there was indeed an instance running, but in the task manager it was far down the list.
That said, I don't understand why this instance is there because I only run PFOA once, obviously.
