Windows XP is now retired and no longer supported by Microsoft.

But you can still run vna/J on an PC running Windows XP if you follow these instructions:

I do not recommend running PCs on Windows XP as there will be no longer security updates for the operating system.

Also I do not recommend to user older JAVA versions, as Oracle may no longer release security updates for these runtime environments.

If you encounter problems running vna/J, feel free to contact me.
