IMAQ_USB - 1074396024 (Minimum coverage value should be greater than zero)

[Neat]

Hi,

I'm having problems to use an USB WebCam when I try to run an executable file in a PC that don't have LabView installed. The error code that appears is 1074396024 (Minimum coverage value should be greater than zero).

When I run it in a PC that has Labview installed, everythings works great!

Anyone have some idea to help me? The example program is attached!

Thks

Hi Neat,

To run your executable in a PC without LabVIEW you must install LAbVIEW Run-Time Engine and Vision Run-Time Engine.

Vision Run-time Engine require license.
