I have both Acrobat 6 and 7 installed.

I want pdf's to open in Acrobat 6 when I double click on them.

I select a pdf, press cmd+i, and set the default application to Acrobat 6.

When ever I click Change All, it sets the default application to Acrobat 7. I've tried this on multiple machines, and it always produces the same result.

I'm running OS 10.4.8.

Any suggestions?
