Copy one vi to another PC - Run but not set or read properly

[Milton]

Hi dears,

I would like to ask some help. I am beginner in Labview. One colleague wrote one vi to control two instruments. This vi works properly in the PC, where it was wrote.

I copied that vi to another PC. It runs there, but doesnt acess properly one of the two instruments (using GPIB). It calls both instruments(I checked with VISA). Using the VISA properties, I set some parameters of the instrument. But the vi can not set or read the right values. Or no set and read wrong values. How could I do? Do I need upgrade parameters or paths? I have not idea what I could do.

Please, thanks for your help,

Grettings,

Milton
