On a Windows XP system are installed Adobe Reader 6 and Adobe Reader 9. Both versions are really requiered. AR6 ist the default program for PDFs because this is necessary for a special programm. AR6 is now also the default PDF-application for the Internet Explorer. For other reasons I need the Internet Explorer to use the AR9.
How can I set the IE to use AR9, but keep AR6 the default PDF application for all other programs?
