It downloaded successfully. But when I ran the setup program it gets stuck saying I need to close Adobe Updater. I don't have that program open and don't see it as an option in the folder. Please HELP!! I need this CS4 application to work today.
Something might not have installed right before. Go to the following page, run the tool and then try running the installer again.
If you still run into issues Adobe offers free installation support to all customers. You might want to consider giving them a call.
Open up your task manager (Ctrl+Alt+Del if you're using Windows) and look there for the Adobe Updater. If it's there, end the process and try to install DW4 again.
