Why do I need Internet Explorer to use the Adobe Acrobat eBook Reader in Windows?
The Adobe Acrobat eBook Reader for Windows requires components that are installed with Internet Explorer. You must install Internet Explorer 4.x or later for the Adobe Acrobat eBook Reader to function properly, but you can use another browser to access the Web.
Note: If you do not install Internet Explorer 4.x or later, you may receive the error, "Unhandled Exception," when trying to certify the Adobe Acrobat eBook Reader.
