The short answer is, unfortunately, no.
In the case of Windows XP, even the manufacturer (MS) has stopped supporting the OS, so it can not be guaranteed from a security point of view. Therefore, currently, JANDI PC program is not supported in Windows XP.
If you need to use it, you can use the Chrome browser. However, Chrome does not support XP since 2015 but it is possible to use it.
There is one web browser that supports XP, which is Opera (http://www.opera.com). So please use this browser if you need to use JANDI on Windows XP.
