What DotFix NiceProtect is
DotFix NiceProtect is Windows software for protecting native applications against decompilation and reverse engineering. It supports x86 and x64 EXE, DLL and OCX files, including applications made with Visual C++, Delphi, C++ Builder, Qt, VB6, MASM and Free Pascal. Protection options include moving selected code into a custom virtual machine, transforming native instructions into generated sequences, and obfuscating RTTI and metadata for Delphi, Free Pascal (Lazarus) and Visual Basic 5.0/6.0 applications. Its packing process treats resources separately, compresses and encrypts code and data sections, and creates a unique loader for each build. The loader includes checks for active debuggers and tracing. Static analysis can identify an executable’s compiler and existing packers and show PE structure details. A command-line interface and console version support build scripts, batch work and headless CI/CD servers. A free demo is listed as version 26.1 with a 6.2 Mb download. Individual Standard License costs $149, paid once and includes one year of updates and support.
