The InstallAnywhere wizard is not fully accessible to screen readers.
To use the installer with a screen reader you must use console mode installation from a command prompt, specifying the -i console option.
Console mode displays text over multiple screens, and enables you to make choices during the installation process. The command prompt interface does not provide a cursor for navigating over the displayed text. When you use the JAWS screen reader you can repeat the displayed text with the command used for reading the current window (key combination Insert+B).
installer -i console -l fr
