Could not get CVI .NET error description

[Vincent_Gx]

HI,

I had delevoped some dll with vs2008 c# language, and generated a wrapper in CVI by [tools-->Create .net controller..], and used this wrapper to make a program. The program is running fine in developing PC, but when I deployed it to target pc without cvi installed, I was getting this error message:

"Could not get CVI .NET error description. A .NET Framework version 1.1 or higher, or the CVI .NET modules may not be installed on your system. If not already present, install the required .NET Framework. Then repair the CVI Runtime Engine installer."

I'm pretty sure that .NET Framework is there, and I did intall .NET framework before intalling my promgram. But the target PC still complaining this error. judging from the error description, most posibility is missing CVI .NET modules, so my question is what is CVI .NET modules, how do I deploy them to target PC?

Thank you in advance,

Hello Vincent!

I would like to ask you to provide more details about your setup, so that I can understand the problem better:

1. Which version of CVI are you using to generate the CVI wrapper?
2. How are you deploying your program on the target PC? Did you create a distribution (Build » Distributions) for it and installed that distribution on the target PC? If so, which components have you selected in the Edit Installer » Drivers & Components list? Have you selected the .NET Support module?
3. Are you using the .NET Framework version required by your program on the target PC?

This solved forum discussion might also be useful for your symptom. It might be closely related to what you're seeing on your machine: http://forums.ni.com/t5/LabWindows-CVI/Could-not-load-required-CVI-NET-modules/td-p/1113345

The discussion thread is also pointing to a KB, which sounds fairly close to the problem you first described, in http://digital.ni.com/public.nsf/allkb/71593D05E9A2B787862570D1006D012A also providing a a solution to the problem.

I hope this helps!
