Go to Windows Update and make sure that all versions of .NET are installed.

Sorry for my ignorance. If I type:


print System.Version()


I get: 0.0


This in the machine where everything rules (I don't have access to the others from home)

Do you have the same versions of .NET installed on both machines?

Dear all,

I'm a newbie in pythonnet and I have the following problem.
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,
