It would help to know what DLL you're loading. Are you copying the exact same DLL file from one computer to the other, or referencing something that's already there? It may be that the DLL you name is statically linked to another DLL, and it's the second one that's causing problems. In that case, even copying the file across won't solve the problem. Look for a DLL dependency tree program (you can find them at the other end of a web search) and see if you have versioning issues. This isn't actually a Python problem, it's all to do with the loading of that DLL. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
