What it is
DotFix NiceProtect protects compiled Windows EXE, DLL, and OCX files against code analysis and cracking. It applies protection directly to native machine code, usually without source-code changes or third-party runtime libraries. Selected functions, conditions, and loops can be virtualized through a custom instruction set or mutated while preserving behavior. Anti-debugging checks make inspection more difficult, while separate packing of code and resources supports ASLR and DEP. Each protection run creates a new loader and unpacker core with a non-fixed layout and internal data tables. The obfuscator can rename Delphi and Free Pascal classes, objects, events, nested elements, and RTTI structures. Visual Basic 5.0/6.0 names for forms, modules, classes, controls, events, and procedures can also be rewritten. Supported toolchains include Delphi, RAD Studio, Free Pascal, Lazarus, C++ Builder, and Visual Basic. Windows x86, x64, and ARM64 are supported. A free trial is available. Standard (32-bit) costs $149, paid once.
