Hi,
The first thing you need to check is make sure the same DAQ driver is installed on both computers. Then, you need to make sure that you can view the device in the Measurement and Automation Explorer (MAX). Once you can do this, then you will need to make sure the LV Run-Time Engine is installed on the stand-alone comp. This needs to be the same version as LabVIEW that is installed on the computer where the application was developed.
I hope this helps.
