VISA Serial Port Problem

[dana 31]

My VI communicates with my instrument using the serial port. I configure the port using 'VISA Configure Serial Port', creating a front panel control for the input 'VISA resource name'.
When I create an executable with the Application Builder, and install the exe on another pc, I can no longer communicate with the instrument and the VISA Resource control is greyed out, i.e. I cannot select between COM1 and COM2 etc. However, the control and the VI work fine as an exe when run on the original pc.
Original PC = win2000, labview 6.1, other PCs where exe installed = win98 & win95.
Any suggestions ?

You have to install VISA on the other PC. You can include VISA run-time installation when you create the installer for the VI. You can find the run-time version here. The other option is to not use VISA for serial communication. The old serial driver requires a small file called serpdrv to be installed in the same folder as your application. However, there was a recent discussion about the future of serpdrv and whether it will be part of future releases.
