  1. Hi Priti,
    The HTML/ARIA aspects of the tool only work with IE and Firefox currently. The ‘desktop mode’ that exposes MSAA/IA2 info works on all browsers (if they expose info via the MSAA/IA2 Accessibility APIs).

  2. Terms of Use> whether I don’t get what a freeware is or what a commercial use is?

    Could you please clarify this:
    Can I use it freely while working and being paid as an accessibility expert on a client’s project? Can I embed it in another software and sell the whole? I guess this Terms were written to avoid the latter case, but I’m afraid it’s not so obvious.

  3. Hi Andreas, ARIA attributes are defined in the WAI-ARIA specification. What is defined in HTML5 is on which HTML elements they can be used. The AViewer will display information about what role and aria-* attributes are present on an element.

  4. Hi Felipe, If you are an individual using the tool, there is no problem, if you are company that deploys multiple copies of the tool for use by your employees, contact Brian Landrigan to dicuss licencing terms.
