Hmmm, here are a couple more ideas: Are both machines 32 or 64 bit? Are both copies of Python also 32 or 64 bit? You could be attempting to load a 32 bit dll on a 64 bit machine, or visa versa. In theory, if the assembly is C#, or VB.NET, you can compile the assembly for "Any CPU", and it should work on both. Alternatively, you could use 32bit Python on both machines, and explicitly compile the assembly for x86 (32bit).
I have also found that loading assemblies is also much more reliable if the internal namespace of the assembly matches the name of the resulting .dll.

I am trying to load an assembly from a .dll file. Currently I am running the trials over Windows XP and python 2.6.5 and pythonnet version 2.0 alpha 2 On my computer there is no problem on loading the library. However in another computer (notebook) with the same installation (the library in the path etc) the system fails to do the AddReference. However if I ask for findAssemblies the system is able to find it. I can add the Reference to the test dll that come with the pythonnet. I was assuming a mismatch on the .net versions, but then: why can l loaded from some computers and not from some others? Kind regards, -- Juanma
