AfterEffect - Clear cache script at shutdown

Hello,

I am looking to start a disk cache cleanup script when closing After Effect.

The script is fully functional when I run it from the script executor.

However, when it is started at closing, I have the message displayed but nothing happens at the cache.

I think the problem is in the window that asks for confirmation before deletion (when it is started manually).

Do you have any ideas or solutions?

Here is the script (normally valid for CS6, CC) :

{

app.executeCommand(10200);

alert("Clear cache !");

}

Thank you in advance.

Have a good day.

Guillaume.
