Recently, when I click on the “Print” button (after having entered the .pdf doc title), I get a pop up that says that Microsoft Office Ultimate 2007 is installing. I have to hit “Cancel” four times to kill it. Since it started, I have upgraded to the latest version of pdfCreator but it’s still the same. I’m running Vista by the way.
this is usually related to a broken or incomplete .msi installation.
