We have created the demo version of the ABACUS so you can see for yourself the features and ease of use the ABACUS offers. The entire demo is in one exe file. What we recommend is make a new directory (Abacus, AbaDemo, etc.), place the downloaded exe file in this directory, and run it there. By default, any files the demo creates will be created in the directory in which it resides. This way, when you are done with the ABACUS demo, simply delete the directory you created and all its contents, and the demo will be all gone. No complicated install or uninstall procedures, and no annoying files sprayed all over your system.
