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:
- Download the JAVA 7 JRE from Oracle
- Install JAVA 7 on your PC
- Download the application JAR for vna/J which is explicitly compiled for JAVA 6. For vna/J 3.1.7 this is the file vnaJ.3.1.7.J1_6.jar in the download directory of vna/J 3.1.7.
- Launch vna/J as described in the User Guide.
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.
