Old control/updater programs are usually written in VB6, Delphi/C++ Builder or .NET VB, C#. DetectItEasy can show PE32 info which usually and almost allways shows which development tool/framework is used. DetectItEasy strings function shows ASCII strings inside .EXE file. Sometimes there is code embedded inside exe, usually as Motorola S-Record format. E.g. with Python script is easy to extract it and remove unnecessary characters. import re re.sub(r'[^S0-9A-F\r\n]+', '', text) ...  or use Linux stings command.  Installers are usually msi or innoextract. Can be extracted e.g with unzip, msiexec, msiextract (Linux) or innoextract (Linux). Sometimes embedded code is inside in a one of the extracted files. SRecord is a set of tools for inspecting/converting etc. S-Record data. VB6 programs can be further examined e.g. with VB6 decompiler lite. .NET programs, dotPeek can export to VS solution. Even in deobfuscated .NET programs it is possible to find some quite clean code (...

Detect It Easy   De4dot   dotPeek export to VS project. VS 2026 converted successfully to .NET 4.8 level. Weird and obfuscated source files but also a dir in project that contains clean code files. Changed configuration to x86.   Build failed with many C# 7.3 nullable disable errors. added to .csproj     <Nullable>Enable</Nullable>     <LangVersion>preview</LangVersion> still one CSC nullable disable error c# 7.3 changed to wrong configuration x86 -> x64 and back to x86 then clean and successful build.
