Not able to capture trigger in exe.

Hello 

I am using LabVIEW 2012 SP1.  The hardware is PXIe 6363 card . 

I have a VI which starts acquiring data on  Digital trigger( falling edge). The digital trigger lasts for around 100ms.

The trigger works perfect in when run the VI. But when I make the application exe, the trigger is missed and I get timeout error.

What is the difference between the VI and the exe?

In the VI , the trigger is captured everytime and data is acquired but this does not happen in exe. Please let me know.
