Playing exe generated by CS4-AS3 under Windows 10

Hello,

I want to run automatically under Windows 10 an .exe file generated by the publication of an AS3 program (under CS4)

So I use the application scheduler of Windows 10 to launch automatically the exe.

Everything works fine but I cannot use the keyboard to send event to my exe program.

I need to click on the part of the screen where my program displays,  in order to bring the" focus on it". Later the keyboard is received.

What can I do to have the focus automatically ?

Thanks

.
