Port I/O application missing external code

[MarcelJ]

Hi,

I wrote a simple application using the port VI's.
I put a shortcut to the application in the startup menu so that it would start at startup of the PC.

Unfortunately at startup I get an error message of Outport8.vi No. 25 "External code not present"

I did include port VI support in my installer.

When I start the application from the menu manually, the application works just fine.

What could be the issue ?

regards,
Marcel

Well, after some time looking for the issue I gave up on the port VI's.

I have moved to calling the following inpout32.dll and it works well :

If anyone knows how to solve the Labview issue, I'd still be interested to hear about it though. btw, I tried in Labview 7.1.1, which perhaps makes a difference too.

regards,

It's a bit strange, but when I build the application on another development PC it works well.

Both machines use Labview 7.1.1 but there's a difference. The CVI runtime engine installed on the failing machine is version 8.0 and on the PC that does the job well 7.1.1.

Since I have other bad experiences with mixed versions of NI products, I guess this is the issue.
