In Adobe Reader 8.1.2 I can't open zip files attached to pdf files any more. I followed some hints in the knowledge base but none of them solved my problem. The registry editing suggestions for rel. 7 doesn't apply to version 8.1.2. and setting the trust option didn't help as well.
In brief what are the steps in order to allow reader 8.1.2 to open zip attached to pdf files???
