I have developed a simple application on LabVIEW 6.0.2 and using application builder to make an exe. When trying to run the exe on a different machine, the dropdown arrow on the VISA-Resource control is disabledand when the application is stopped, pressing the arrow causes the application to generate an invalid page fault at 0177:30164426 in the LVRT.dll Using NI-Spy it can be seen that when the application starts, the call to viGetAttribute returns an error - VI_ERROR_NSUP_ATTR.On the target machines we have NI-488.2 version 1.6 and NI-VISA 2.01, and on the development machine NI-488.2 version 1.6 and NI-VISA 2.5. Both machines are running Windows98.I have tried installing the run-time version of NI-VISA 2.5, but then the application crashes when it loads.~Kevin"

VISA Error with Built application

A few suggestions:

1. Make sure the 6.0.2 runtime engine is on the target machine.

2. To reduce the number of variables I would have the same version of NI-VISA on the target machine that is on the development machine.

3. Be sure to copy your visaconf.ini file to your target machine.

Hope this helps.
