## **DotFix NiceProtect** : Advanced Protection for Windows Software

![DotFix NiceProtect Box](https://www.niceprotect.com/images/box.png)


Multi-layered protection for native **32-bit and 64-bit** applications built with Visual C++, Delphi, C++ Builder, Qt, VB6, MASM, and other compilers. Combine [code virtualization](https://www.niceprotect.com/help/code_protection.htm) with specialized [metadata obfuscation](https://www.niceprotect.com/help/obfuscation.htm) engines.

### Beyond Standard Protection

Standard packers only compress your executable, leaving the code logic intact after unpacking. **DotFix NiceProtect** goes deeper. It reconstructs and secures the internal logic of your application using advanced [Code Virtualization](https://www.niceprotect.com/help/code_protection.htm) and [Mutation](https://www.niceprotect.com/help/mutation.htm) engines. Whether you develop in C++, Assembly, or Pascal, your algorithms are converted into a unique virtual bytecode that never runs directly on the CPU, making it invisible to standard debuggers and disassemblers.

**Developed continuously since 2003:** The early product line, now known as **DotFix Protect**, evolved into **DotFix LiteProtect** in 2004. One of its distinguishing capabilities was masking the entry-point signatures used by tools such as PEiD to identify packers and protectors. As the technology grew into a broader software protection platform, it became **DotFix NiceProtect** in 2006.

#### Universal Protection


Works with native Windows compilers including **Visual Studio C++, Qt, Delphi, and C++ Builder**.


Our **polymorphic engine** generates a unique protection structure for every build. Combined with strong **[anti-tamper](https://www.niceprotect.com/help/protection_options.htm)** and **anti-debugging** systems, it helps resist tracing, debugging, and decompilation.

#### Delphi & VB Exclusive

**An exclusive advantage:** For **Delphi**, **Free Pascal**, and **VB6** developers, NiceProtect provides deep **[RTTI obfuscation](https://www.niceprotect.com/help/obfuscation.htm)** that is not available in other publicly released software protectors.


NiceProtect physically renames classes, forms, events, and object names directly in the binary. Hackers see a chaotic structure instead of meaningful names like `TfrmLicense`.

*Built by the developers of **[VB Decompiler](https://www.vb-decompiler.org)** — informed by first-hand reverse-engineering expertise.*

 

#### Key Capabilities:

- **[Code Virtualization](https://www.niceprotect.com/help/virtualization.htm) :** Secure critical logic with a custom VM.

- **[Metamorphism](https://www.niceprotect.com/help/mutation.htm) :** Complex instruction morphing.

- **[Compression](https://www.niceprotect.com/help/packing_options.htm) :** Packs code, data, and resources.

- **x86 & x64 Support:** Full 32/64-bit support (EXE, DLL, OCX).

- **[SDK Markers](https://www.niceprotect.com/help/virtualize_markers.htm) :** Mark code sections for virtualization directly in your source.
