It feels silly to not be able to figure this one out, so here goes: I've got two versions of QuarkXpress (3.32 and 4.11) on two computers. The computers are identical in software and hardware. They're G4 dual 500s running 9.2.1. <br><br>Funny thing is, when I double click a Quark 4.11 fiile on one computer, Quark 4.11 launches. On the other computer, a double click of the same Quark 4.11 file will cause Quark 3.32 to launch and of course not be able to open the file. <br><br>Rebuilding the desktop hasn't helped. File Exchange settings have been double checked. I can't help thinking I'm missing something obvious. Must've been the weak coffee this morning. <br><br>Any smart, kind soul have an insight as to how to have control over which version will launch?<br><br>Many thanks in advance,<br>Jesse<br><br>

Only thing that comes to mind is that the app isn't backwards compatible. I think the same thing happens with Word. Word 2001 can open word 6 files, but Word 6 can't open Word 2001 files.<br><br>And that's true too.--Shakespeare, King Lear

Is there a reason why you need the older quark? Just delete the old one, and if it still doesn't work, then rebuild the desktop. Otherwise, you can make droplets that will convert files to quark 4 file types. Good luck.<br><br>--John Bailey ([color:red]Bdog</font color=red>)<br><br>Email Me! ---> bdog_111@yahoo.com

John's comment about Quark Xpress 3.32 is a good one. Sooner or later you're going to have a problem due to different versions. You don't have to trash it. If you're concerned about needing it for some reason just drag and drop it on DropStuffit.<br><br>(directory problems, among other things, can be endemic if you have multiple copies of different versions of same app.)<br><br>
