DOWNLOAD the novagps

Are you interested in self improvement? If so here's an application in progress free for you. You'll need Java installed on your machine. If you are using windows (not XP) you probably have java installed already.

First download the file here. 1. unzip the file
2. change directory into the directory where you unzipped it.
3. There should be a sub-directory called 'Tree' where you are.
4. Run the Profile.bat or the RunTree.bat.
5. now that your environment is set up just type:
java Tree.Tree

Trouble shooting: if it's not coming up you're probably in the wrong directory. Make sure you are in the directory where the profile.bat file is.



Have fun!
