What DotFix NiceProtect is
DotFix NiceProtect is Windows software that protects native applications against decompilation and reverse engineering. It handles x86 and x64 EXE, DLL, and OCX files built with Visual C++, Delphi, C++ Builder, Qt, VB6, MASM, Free Pascal, and other compilers. Selected code can run inside a custom virtual machine, while native instructions are transformed into generated sequences. RTTI and metadata obfuscation covers Delphi, Free Pascal (Lazarus), and Visual Basic 5.0/6.0. Multi-stage packing separates resources, compresses and encrypts code and data sections, and creates a unique loader for each build. The loader includes anti-debugging and anti-tracing checks. Static analysis identifies compilers, existing packers, and PE structure details. Command-line and console versions support scripts, batch processing, and headless CI/CD servers. Support covers Windows XP through Windows 11. Individual Standard License costs $149, paid once, with one year of updates and support. A version 26.1 demo is available.
