How do I set reader 9 as my default reader? I also have Acrobat 6 running & when I attempt to read a document it defaults to Acrobat 6 & I get the prompt that I need Reader 9 or later to read this document. In sum--I wish to have both reader 9 & acrobat 6 on my system, but have reader 9 used as my default reader.
You don't specify your platform, and this is important here. Adobe strongly advises not having both Acrobat and Reader installed in the same Windows machine, although it doesn't matter in Macs.
