.NET Exception when opening a VI

[Walker34]

Hello,

I use a .NET dll in my project. This dll and my project do a good job with Labview 2013 on hundreds of machines.

Now I migrated on Windows 10 and Labview 2017 32bits. And there is something strange ; when I load (=when I open the file) a VI containing this DLL, there is allways an error of .NET that says that .NET made an exception and the DLL could not be loaded. See attached.

I thought that the DLL was the problem because it is done by small company. But now I tested with a very common DLL from Visual Studio packages : IonicZip. It makes the same error.

Has someone some idea about solving this issue?

I can't open your attachments at the moment. But a quick guess - does your assembly target .NET 3.5? Windows 10 does not come with this pre-installed unlike Windows 7 SP1 so if your require it you need to install it manually (its in the Features list and you can tick this if you are connected to the internet; otherwise use an offline installer).

Hey you were on the right way, I launched a .NET Framework Repair and it worked.

Thanks!
