You can't install anything? Or only these two apps? What do you mean by you can't use anything?

Nothing works? That can't be possible. Are you logged in as administrator? Where did you get these disk images from?

I cannot open ANY .dmg files "disk image failed to mount"

Have you installed the recent Leopard updates successfully? Message was edited by: Reply Helpful Thread reply - more options Link to this Post. You were probably running them from the mounted disk images somename. Your programs are trying to mount the disk images the programs came on. You were supposed to drag the applications out of the disk images that were mounted on your desktop like CD's and put them into your Applications folder.

Then drag them to your Dock to make a shortcut on the Dock to be able to quickly launch them. If you didn't drag the applications out of the mounted disk images, then the applications are trying to launch, but the images are not mounted anymore. Reinstall the applications properly from the disk images. I tried to repair the permissions but I am not able to click on it.
