I have Adobe Acrobat Writer 6.0 (paid version) and the free Reader 9.0 on the same machine. I don’t need to upgrade the Writer, so 6.0 works for me.
In Windows Explorer I have PDF files associated by default with Reader 9.0. But when I open ZIP archives containing PDFs (as useless as that is, I know, but I don’t ZIP .PDF files) they open in Acrobat Writer 6.0. I don’t need or want that, but I also don’t want to uninstall Writer 6.0 or WinZIP.
How can I force WinZIP to open the PDF files with the current version of the Reader application?
