AutoLISP Source Protector Pro

Protect and distribute your AutoLISP routines with confidence using AutoLISP Source Protector Pro—an easy-to-use utility designed for AutoCAD and Visual LISP developers.

This program converts readable .LSP source files into compiled .FAS files, helping prevent customers and unauthorized users from viewing or modifying your original code. Its organized DCL interface lets you compile multiple routines, select a protection mode, create source backups, verify completed files, and generate a detailed build report.

Key features:

• Compile individual or multiple LSP files

• Create protected FAS distribution files

• Three Visual LISP compiler modes

• Preserve your original source files

• Optional automatic source backups

• Existing-file overwrite protection

• Selectable output folder

• Completed-file verification

• Detailed TXT build reports

• Clean, professional DCL interface

• Designed for AutoCAD 2002 and later Windows versions

Your download includes:

• AutoLISP Source Protector Pro LISP file

• Professional DCL interface

• Complete installation and operating instructions

Important: This program uses the Visual LISP compiler included with supported Windows versions of AutoCAD. The Visual LISP IDE must be available and open during compilation. FAS compilation protects source-code visibility but is not a licensing system or a guarantee against every form of reverse engineering.

Only compile programs you own or have permission to distribute.
