Enable debug output for detailed information

Hi guys,
My post here is about a problem that I meet while using our office inventory application, in the middle of my work I received an error about debug. Please see picture below for your guide.

D3D9 Application
Generic application error. Enable
debug output for detailed information.
This program will now exit.
The error message above is new to me, since this is my first time to encounter such message, in regards to what it suggests about debugging task, I am not familiar with this task, I am now asking for some advice on how to deal with this error message. Do I need to debug? Please do some share on my post, thanks a lot.
