The previous module came from the SR Research thread which contained links to the different platform specific pylink. I downloaded win32.

When importing manually, it works for Vizard4 but not at all for Vizard5. I have eliminated the possibility that it could be looking elsewhere by specifying the exact file path also.
I would prefer to install pylink using the package manager as this seems like the "proper" way to do things. FYI - When I did this, I downloaded Pylink 0.3.2 through the package manager interface. I saw no other versions available.
