ActiveX control is not working with windows NT

[terryallen1981]

I've have a stand alone application which uses an activeX control.  The application was compiled using Labview 7.1 on a Windows XP machine.  The application will run without any problems on Windows XP and Windows 2000, however the activeX control will not work with Windows NT 4.0.  The activeX control is registered, and I have also compiled the application on a Windows NT 4.0 machine.  I do not receive any error messages, the application will start but will not communicate with the activeX control.  Does anyone have any suggestions?

Hello,

Have you tired running the VI by itself (not exe) on the NT machine? Make sure you are doing adequate error checking in your code. It could be possible that the application is generating an error which in not handled appropriately. Also which service pack do you have installed on the NT machine? Please look at the release notes for LabVIEW 7.1 here.
