I have a user who has Distiller 6.0 & Reader 9.0 on his laptop. On a specific web site he is trying to download a pdf document, the computer defaults to distiller 6.0 and the web site refuses to open the document, stating that Reader 8.0 or 9.0 cannot be found on his computer and is required to view the document.
I have changed the default for the pdf's by right clicking on a PDF document and making the Adobe Reader 9.0 as the default and checked the box to "always use selected program to open this kind of file".
Any help or ideas would be grateful.
Maybe starting Acrobat 9 (NOT Distiller 9: this is an extra component
of Acrobat, and not involved in opening PDFs) will help. But overall,
mixing releases and Acrobat/Reader on the same computer isn't
recommended for this sort of reason.
