DotFix NiceProtect vs PELock

DotFix NiceProtect protects native Windows applications against decompilation and reverse engineering. It supports x86 and x64 EXE, DLL and OCX files, with applications made using Visual C++, Delphi, C++ Builder, Qt, VB6, MASM, Free Pascal and other compilers listed. Protection options include virtualizing selected code in 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 multi-stage packing handles resources separately, compresses and encrypts code and data sections, and creates a unique loader for each build. The loader includes anti-debugging and anti-tracing checks that may end the process when tracing is detected. Static analysis identifies an executable's compiler and existing packers and displays PE structure details. A command-line interface and console version support automated scripts and headless CI/CD servers. Individual Standard License costs $149 as a one-time purchase and includes one year of updates and support; a free demo is available as version 26.1.

PELock protects compiled 32-bit Windows applications against cracking, tampering, and reverse engineering, while providing software licensing tools. It protects Portable Executable formats including EXE, SCR, DLL, OCX, CPL, BPL, DPL, ACM, and AX. Anti-debugging methods detect cracking tools and block their actions. The license key manager handles users and keys, generates and verifies RSA-2048 keys, and can block illegally shared keys. Trials can be limited by days, executions, an expiration date, or minutes of use. A virtual DLL binder combines an application and libraries into one EXE, loading those libraries in memory without writing them to disk. SDK examples cover C/C++, Delphi, Lazarus, FreePascal, PureBasic, PowerBASIC, D, and Assembler. Plugins can add compression, detection, licensing checks, and loader functions. The maker lists Windows support from Windows 95 through Windows 10 and Server 2003 through 2012, with 32- and 64-bit support. Pricing starts at 59 one-time; listed licenses cost 159.00 USD or $299, paid once.
