Perfect solutions

for software protection

and source code recovery


VB Decompiler

VB Decompiler allows you to quickly and easily decompil—É parts of Visual Basic 5.0/6.0, Visual Basic .NET and Visual C# (32 and 64 bit) projects that have been lost or damaged.


DotFix NiceProtect

NiceProtect provides obfuscation, code virtualization, packing and anti-debug techniques to safeguard your x86 and x64 Windows software from analyzing, reverse engineering and cracking.


VB AntiCrack

VB AntiCrack protect all strings within Visual Basic 5.0/6.0 source code and prevent analyzing the program through searching string references and reverse engineering.


DotFix LiteProtect

DotFix LiteProtect is a small software protection tool that employs numerous anti-unpacking techniques. It safeguards your files from being analyzed by unauthorized users.


Welcome to the DOTFIX Software official website!

Our team has been developing advanced reverse engineering and code analyzing tools for more than a decade. Our products, which include decompilers and code analyzers, have won recognition from programmers around the world as being handy, easy-to-use, high-performance solutions. Making these types of tools is our core competence. Thanks to our solutions, major antivirus vendors can analyze malicious code and respond promptly to malware threats. A great number of small software developers are grateful to us for the opportunity to recover their lost development codes due to hard drive failures or malware attacks.

Now, our main focus is on developing VB Decompiler, a decompiler for all existing Visual Basic applications that supports Visual Basic 5.0/6.0 (including P-Code and Native Code), Visual Basic .NET and Visual C# (MSIL code disassembling and decompiling also supported). We are also working on a decompiler for Delphi and Free Pascal applications for internal needs.

Given our impressive experience in reverse engineering, we have developed several tools to protect program code from unwanted analyzing or cracking. Alas, almost anything that is available for the antivirus industry or bona fide programmers can be used by bad guys as well. To help the developers, we offer DotFix NiceProtect - a unique software protection platform for preventing code analyzing, decompilation and debugging. Also our solution supports code virtualizing (for any native language compiled files) and obfuscating (protecting from decompiling and analyzing) the code and internal structure of your Delphi, C++ Builder, Free Pascal and Visual Basic applications. This software protection suite has been popular among software developers for some years because it is an effective tool that doesn't have any strong rivals.

The reason for the lack of competition is simple: To make a good obfuscator, you need to be able to check the program file for any parts that allow the attacker to decompile it and modify them in such a way that decompiling the program becomes unfeasible. But you can do this only if you have a decompiler for every compiler and every programming language! Understandably, it is unlikely that protector developers would want to spend years on creating such a software protection platform. As for us, each of our decompilers is just another project, and we successfully use our research results in other areas as well.

Our company provides one year of free technical support for all software tools we offer. After that, customers can renew their support at a discounted rate. We understand that different people use our products in various ways - from educational purposes at home to integral parts of business processes in corporations. That's why we have flexible pricing policies tailored specifically for each type of customer.

No matter who you are or how you use our software, we value long-term relationships with all of our customers!!
