.NET DLL works with Labview 8.5 but won't load properly in LV14

[cotani]

I have a customer supplied Labview example project and .net DLL for a temperature and humidity sensor. They provide a compiled .exe example that uses the labview 8.5 run time engine. That exe is able to read the sensor properly using the DLL. 

When I open the identitical source code in my LV14 and run the same application I get the following error.

When I try to add a .net constructor node on the block diagram I get the following error when I try to load the DLL in the contructor node. 

Is there a reason why a .net DLL might work in LV8.5 and not in LV 14? Is there a way to work around this?

Can it be different .NET version each labview loads by default?

I've gotten error 1386 in the past on DLLs that just couldn't open because another program had a lock on them.  I don't suppose you're trying to do this at the same time you have the EXE open, or when any other program might be using the DLL?

When researching the problem I also read that the error can occur when they're on a network drive and not a local drive.  Is that the case?

BINGO!

I ran through this tutorial on the link you posted and now all is working as expect. Thanks!
