Is it possible to buy the program, on a disk , and if so how can this be achieved?
How is the payment done, and the price?
No, it's not possible to buy the application because it was released in 1994. There is no possibility to download or obtain it on a disk. I recommend using another application from this category instead of using a product from 1994. There are other more advanced from every point of view. Use the database of Software Informer to look for another application from this category. I am pretty sure you'll find another one to suit your needs.
