I knew this was a tricky one and so far no one has figured it out. This does not work. As a guest, you can browse and view the various discussions in the forums, but can not create a new topic or reply to an existing one unless you are logged in. Reinstalling the drivers made no difference, but editing the Path variable as you suggested solved the problem instantly. It has puzzled Canon, nothing in the forum so far has a solution and I am puzzled as I have spnet many hours on this. I am fairly knowledgable with PC’s but this one stumps me. Re-boot the computer no help.
