OK. So there is some confusion as to how 7.0 got on to the iMac and not 7.3. Try this.
1. Move the entire QuarkXPress application folder on to your desktop. ZIP it and put it somewhere safe then delete the folder (not the ZIP file).
2. Copy the entire QuarkXPress application folder from the G4 to your iMac. You'll probably have to network them since the G4 is going to be PPC and the iMac will be Intel.
3. Place the folder you copied over into the Applications folder on the iMac.
4. Open that folder and find the following folder inside: For System. Inside that folder will be this app: QuarkXPress Components
5. Double-click on QuarkXPress Components. Let it reinstall the components.
6. Delete the following folder Library>Preferences>Quark. This will delete any activation information
7. Delete the following folder ~username>Library>Preferences>Quark>Quark 7.0. This will delete all preferences.
8. Restart your Mac.
9. Restart the QuarkXPress application. You will be asked to activate your copy of XPress again. Do so and you should be good.
At this point you should be at 7.3 (which was copied from the G4). If you want to update to 7.5 then you can do that. The issue of unreadable DMGs sounds to me like the download is not completeing (I've had that happen with slow DSL connections).
Hope that helps.
