During the installation i get the message "Cannot find the PAPAI Tree"

Cause:
The installation program cannot find the description of the PAPAI Tree (the file papai.dat)

Solution:
This is normal when you install the system for the first time - then there is no PAPAI Tree. Answer "Yes" to continue the installation.
If you get this problem when installing an upgrade or an add-on package, you probably have an incorrect pathname in the java command that starts the Toolbox. For Windows systems this is located in the shortcut for the PAPAI Toolbox under Properties | Program. For example java.exe -cp papai.jar papai.papai C:/Papai
C:/Papai is the path name in the command. This must point to the folder where the PAPAI Tree is located.
