I have a user with two versions of Adobe, Adobe 4 (don't ask) and Adobe 7. The require both. The problem I'm having is within Excel 2010. When this user opens an embedded PDF in Excel, it chooses Adobe 4 as the viewer and editor. How would I switch it to automatically select Adobe 7 when double clicking on an object in a spreadsheet? I've already tried to right-click a PDF file (on the desktop) > Select Open With > and double-clicked Adobe 7 with the checkbox "always use the selected program to open this kind of file." When I launched excel to try again it still opened in Adobe 4.
Any help would be much appreciated!
