Error loading DLL with .NET constructor: missing assembly manifest?

[coolhandLV7]

Hello,

I have a device that has a DLL associated with it, when i try to use it in labVIEW i get the following message.  "The module was expected to contain an assembly manifest".  What does this mean and how do i correct the issue?

Sounds like a Keyence driver library. What is the bitness of that library and what is the bitness of your LabVIEW installation?

It might not be a .NET DLL, that error message is one you would get if it's a "classic" DLL.

Try using a Call Library Function node, see if that can use it.  If it came with a .h file, use the wizard to make it easier.
