From April 2014, Microsoft officially ends all support for Windows XP and Internet Explorer 8.
At ASIMUT software we won’t go that far – we will still support running ASIMUT on Windows XP, but we will require you to use either Chrome or Firefox browsers, when using the admin interface. The public interface will support Internet Explorer 8 for some time to come. Our recommendation for maximum performance and usability is to use a modern browser like recent versions of Chrome, Firefox, Safari or Internet Explorer 10 and above.
