AshLPD is an A-Shell/Windows application and does not, by itself, require a license, but to run it on a machine that doesn't already have A-Shell, you'll eventually need an A-Shell license, although it will also run in demo mode. When AshLPD is launched, if the underlying copy of A-Shell is not licensed, the main window will become visible, and a "Register" option will appear on the menu bar. Click the option to go to the licensing screen, which will display, among other things, the license status. Please contact MicroSabio for any questions or problems installing the license.
You can also get to a standard A-Shell prompt and run LICENS.
