Thank you for your post.
You should not have to wait "several days". It appears the download was not complete or damaged. Please download a fresh copy. Once downloaded, reboot the Mac to make sure no other applications are running. Then, install FileMaker Pro Advanced.
If you continue to encounter problems installing, please contact our Technical Support department. If you are located in North America, call toll-free 800-325-2747. Outside of North America, contact the FileMaker office nearest you. There are no charges for installation issues.
