Support for Windows XP
I no longer support vna/J for Windows XP.
Windows XP was introduced 2001 by Microsoft. Finally the support for Windows XP has ended in April 2014 - 13 years - long enough for an operating system in the internet age!
You can download old JAVA versions in the Oracle archives which may install and run on Windows XP - a JAVA 6 runtime should be fine for vna/J.
