EE4 screen capture dieing

Question

Hello,

I am using expression encoder 4 sdk for screen captures.
The program I wrote is used for security reasons to monitor activity on remote client systems (no audio).
I noticed that occasionally while the capture was going and for no known reason the capture
would just stop.
My question is do you think that the event screencapturefinished would be a good way to know when
the capture has died or do you think the event would never be called because it died.
I am having a hard time trying to write this event handler (screencapturefinished) even
with the examples I found on the internet. Does any one know what I could monitor to see if
the capture dies if the above is not a possibility. Working normally the program just monitors
the mstsc process and stops the capture when this process ends. If I could know when the capture
dies then I could kill the mstsc process to force the user to restart.
The one question I found on the forum about screencapturefinished didn't help me.
