Sorry for missing the attachments.
Please find the attachments for the VI, Error message, and the settings that i have.
Error is popping in 2010 LabVIEW.
But I have the same code opened in 8.6 LAbVIEW, it is not popping up the Error.
When i connect the error indicator, it is showing the error in the indicator. But if indicator is not connected, it is not throwing any error message(i.e default LabVIEW Error pop up if error occurs and indicators are unwired).
I checked the settings in Tools-->Options which are set properly.
Please let me know the cause.
