I have an computer that suddenly can only open an .PDF file in Acrobat, and not in Illustrator. We have art files that are in PDF format, and Purchase Orders that are in PDF format. We would just drag the icon over the software we wished to open the file. In this case Illustrator for the art file and Acrobat for the P.O. As of today, PDF's only open with Acrobat and that's it. I know it's probably a setting I'm forgetting. Any help would be greatly appreciated!
You're not giving us enough to go on. What do you mean 'doesn't open'? Do you get an error? Just a blank file? Have you tried opening Illustrator and using File > Open instead of just dragging to the icon?
Just as a guess, you could try resetting your preferences;
1) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (not reversible)
2) Move the Folder (reversible).
By doesn't open I mean, if you drag the file icon over the Illustrator icon, you get the circle with the slash. Meaning this software cannot open this file type. To simulate what we see, think of dragging a file icon over an unassociated program like an image file over word processor program. It will let you know you can't open this file with that software. As for opening the file, yes it will. We just tested it, and it will open the file. I guess the only issue is that dragging the file icon over the program icon suddenly will not work. It's beginning to look like this might be a computer issue. However the only programs affected are the Adobe software. This one is strange, never seen it. The computer is a Windows XP machine with CS5 on it. The artist is used to using a Mac so the drag and drop is second nature, plus she checks in our graphic files against the accompanying P.O. A large percentage of which are Adobe acrobat files. It's just one of those irritating work around issues she shouldn't have to do, and will not have time once our busy season starts. Thank you for all of the help and have a great day.
Did you try resetting your preferences? (see my first post).
If that doesn't help, try logging in as another user and see if it works then. It certainly sounds as if something's gotten corrupted.
