Unfortunately I do not have the Windows 7 version that allows me to operate in Windows XP mode. Fortunately we are Mercedes owners. In addition to posting my question on our website I also contacted Mercedes. They responded with easy to follow directions that work. Here are the directions which others might need in the future.

Using the STAR Classic CD on Windows XP or Windows 7
1. Insert the CD into your CD Drive.
Note: If a page shows up stating that you need Acrobat 4.0 or better, and
you already have it installed on your PC, then ignore the message and close
that window.
2. Double click on the "My Computer" icon.
3. Right-click on the CD Drive icon that is running the STAR Classic CD
and select the "Open" option.
4. Double click on the "Program" folder.
5. Double click on the "welcome.htm" and the STAR Classic program will
run shortly thereafter.
If the above referenced instructions are not successful in allowing you to
run / install the CD, please contact tech support online at
