What exactly return GetManualHardwareID? (SOLVED)

Hello,
I need to know what exactly return GetManualHardwareID function,
if it can’t get HardwareID.

because it’s not = “”

otherwise my functions would work correctly.

Is it possible to return null or undefined or “blank” like a string?

Because there is a problem with some users and I need to know

what exactly return GetManualHardwareID to catch these errors.
I can’t make tests on my PC, because GetManualHardwareID works for my PC.

From Script Function Reference:
“If an error occurs, a blank value is returned.”

What means that?

Sorry I have not completely understood your request. Does GetManualHardwareID not work for you?
