Welcome to the DOTFIX Software official website!

We've been developing advanced reverse engineering and code analyzing tools for more than a decade. Our products have won the recognition of many programmers around the world. Making handy, easy-to-use, high-performance decompilers and code analyzers is our core competence. Thanks to our products, major antivirus vendors can analyze malicious code and promptly respond to malware threats. A great number of small software developers are grateful to us for the opportunity to recover the development code of their long-term projects lost as a result of some sad event (such as a hard drive failure or malware attack).

Now our main focus is to make a decompiler for all existing Visual Basic applications (VB Decompiler), namely Visual Basic 5.0/6.0 (including P-Code and Native Code) and Visual Basic .NET (MS IL code disassembling is already supported). For our internal purposes, we are working on a decompiler for Delphi applications.

It's logical to assume that we have used our impressive experience in reverse engineering to develop a number of tools for protecting program code from reverse engineering and cracking. Alas, almost anything that is available for the antivirus industry or bona fide programmers, can be used by bad guys too. To help good guys, we make state-of-the-art solutions that help them protect their programs from unwanted analyzing or cracking.

We offer you a unique software protection platform for obfuscating (protecting from decompiling) the internal structure of your Delphi or Visual Basic applications, DotFix NiceProtect. This tool has been very popular among software developers for several years especially because it doesn't have any strong rivals. The reason for the lack of competition is very simple: To make a good obfuscator, you have to check the program file for all parts that make it possible to decompile it, and to modify them in such a way that decompiling becomes unfeasible. But that's only possible if you have a decompiler for every compiler and every programming language! Understandably, it's unlikely that protector developers would want to spend several years on creating such software protection platform. As for us, each decompiler is just another project, and we successfully use the research results in other areas too.

With any software tool, we provide one year of free technical support, plus the opportunity to renew the support at a discounted fee. We have flexible pricing policies intended for different categories of customers, from home users who use our products for educational purposes to corporate customers who make our solutions part of their business processes.

We are always happy to have long-term relations with our customers!
