I don't think you are doing anything wrong. I think we saw this problem at work. Uninstalling 6.0 is part of the problem/solution I believe. The 7.0 stuff only works with a clean build on our machines(ie. not an upgrade). We were miffed about it and ended up having to use the Acrobat vb object to create a .ps and then distill it on older installs. Maybe wiping the registry of 6.0 and re-installing 7.0? When you run this manually in Excel does it produce a readable PDF?
