Since upgrading to Snow Leopard, I cannot get any downloaded .dmg files to do
anything. After downloading them, I double click on them and nothing happens. Nothing. No error message. No bouncing dock icons. Nothing. I've tried downloading them using Firefox and Safari with the same results. This is happening with all .dmg files, not just the same ones, so I know it's not unique to a particular .dmg file.
Any ideas or fixes? Anyone else having this issue?

That's controlled by /System/Library/CoreServices/DiskImageMounter.app. Select a .dmg file, CMD+I, and see what's indicated under *open with.* If not that app, then select it, and click Change all. Now, double-click on a .dmg file and all should be well.

Tried that. No joy. Thanks for the suggestion though.
Also, it appears that I can't unzip anything either with the "Archive Utility." This is not good. I don't think I can go much longer with this limitation.
Spotlight won't find the Archive Utility (you can find it in a Finder search window, but only if you tell it to include system files). It should have been installed in /System/Library/CoreServices (along with DiskImageMounter).
It does sound as if your file associations are screwed up. Did you say that the "Open With" for .dmg files was showing "DiskImageMounter"?
You could try doing this, which resets the associations for all applications:
The problem is happening again. There must be something that resets the settings for this issue.
I've also noticed this time around that if I mount a dmg manually with the Disk Utility, and contains an installation package, that it starts the "Installer" utility, but it just bounces on the dock and becomes unresponsive to anything but a Force Quit.
So add that to the list:
- Disk Image Mounter
- Archive Utility
- Installer Utility
I have same problem. Holding cmd-opt-esc you can see the application listed but it's not running at all. with cmd-tab it's not showing up. I have to keep on deleting the 2 pref in the user/pref folder and relog. Any idea? The only thing I did was install 10.6 over 10.5.8. I also reinstall Stuffit Deluxe.
