Problems to find commports in different PCs

Hello,
 
I've got a problem with the VISA serial.
When trying to run my application in other computers, depending of the computer, the application detects the serial ports or not.
In the other computers I have installed LabView Run-Time-Engine. Do I need something else?
 
The computers I've been trying my application run W98 and W2000.
 
The application has been developed on LabView 7.0
 
Has anyone experienced this problem before?
 
Thanks a lot

I use these VIs to find the Comm Ports either all at once or one at a time.

Make sure you've installed either the full VISA run-time engine or when building an installer, add support for the smaller serial only VISA run-time. You may also need to create the aliases "Com1", "Com2", if your application uses them instead of the actual VISA resource names of ASRL1::INSTR, ASRL2::INSTR.

Hello,

as Dennis have commented, you also need VISA Run-Time installed on those PCs. Take a look into this article or KB
