err: Driver status:(Hex0XBFFF0000)

Hi

I am trying to transfered the LabVIEW VI from an old computer with WinXP to a new computer with Win7. The labVIEW version is 7.1.

When I try to run the code in the new computer, I have the following error message:

err: Driver Status: (Hex 0XBFFF0000)Priimary Error (Hex0XBFFF0000)

PS: I have already transfer all the dll file it needs to run the code. Is it because the driver is not installed? If I need to install all the drivers for the instruments, am I supposed to install the drivers the same as in the old system or some new drivers for new system?

Thanks ahead!
