Hi mill008,
Are you trying to install the same setup file on each machine? This error could occur if you did not get a complete download of the setup file.
It is also possible that you do not have enough disk space to run the installer properly - please verify that you have plenty of room on your drive.
Also, do you have Visual Studio 2005 installed on your machine? This will be required to run the setup file correctly.
If you are still running into problems, I would recommend contacting our support team directly. You can send email to support@componentone.com, use the web submission form at http://www.componentone.com/mysupport or call (412) 681-4738.
Thanks!
