DotFix NiceProtect
What DotFix NiceProtect is
DotFix NiceProtect protects compiled Windows EXE, DLL, and OCX files against code analysis and cracking. It applies protection directly to native machine code, so the usual process does not require source-code changes or third-party runtime libraries. Supported applications include those built with Delphi and RAD Studio, Free Pascal and Lazarus, C++ Builder, and Visual Basic 5.0/6.0.
Protection can move selected functions, conditions, and loops into a custom virtual-machine instruction set, or mutate them while preserving their behavior. The software also checks for debugging, packs code and resources separately, and supports ASLR and DEP. Each protection run creates a new loader and unpacker core, with a changing file layout and internal data tables. For Delphi and Free Pascal, it renames classes, objects, events, nested elements, and related RTTI structures. For Visual Basic 5.0/6.0, it rewrites names for forms, modules, classes, controls, events, and procedures. Supported Windows platforms are x86, x64, and ARM64. A free trial download is available. Paid plans start at $149, paid once; license terms and supported application bitness vary by plan.
