I have builded a .NET dll which is a wrapper of the or-tools, http://code.google.com/p/or-tools/, made by google. I import these by "tools->import->.NET controls to pallet->browse" and select the various dll's. When I do this I get the error Translated from Dutch to English it comes to this: "System.BadImageFormatException: Can not load file of assembly C:\or-tools\Google.OrTools.ConstraintSolver.dll or one of it dependencies. This assembly is build by a runtime newer then the currently loaded runtime, and can not be loaded. <append><b>System.BadImageFormatException</b>.My question is why does this error actually occure? Is it mostlikely because I builded it with .NET 4.0? If so, will it help if I build it with .NET 3.5? Or does LabVIEW doesn't support that either? I hope a NI employee can give me some insight :). The dll can be downloaded at: http://code.google.com/p/or-tools/downloads/list

Hi, I think that you have your answer but for more info about the .NET 4.0 and LabVIEW you can read the links which are given below. http://digital.ni.com/public.nsf/allkb/32B0BA28A72AA87D8625782600737DE9?OpenDocument http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/configuring_clr_version/ Regards, Hossein

.NET DLL System.BadImageFormatException

Solved!

I had actually tried the labview.exe.config previously (this method has been suggested many times in other .NET-related threads) and I found that it did not work in this case, so I don't quite know why it worked on your system.
