VB Decompiler History
VB Decompiler v12.3 has been released (January 1, 2024)
What's new in this version:
- New powerful feature to rename variables in decompiled code. You can now
right click on any variable (var_XX in VB5/6 code and var_XX, num_XX,
flt_XX, str_XX in a .NET assembly) and choose "Rename variable" from
the popup menu. All instances where this variable is used will be
automatically updated. You can undo this renaming by right-clicking
on the variable again and selecting "Undo renaming". Each new name
will be checked before renaming to prevent conflicts with keywords
or other variables.
- Increased decompilation speed (Native Code)

style for .NET compiled programs (.NET)

VB Decompiler v12.1 has been released (April 15, 2023)
What's new in this version:
- A new era of .NET decompilation has begun in VB Decompiler! Version 12.1 introduces
the first iteration of C# decompiling from IL bytecodes. Since its
inception in 2006, VB Decompiler has continuously improved compatibility
over time. This isn't standard .NET decompiling using Reflection classes;
all .NET decompilation within VB Decompiler is written from scratch and
doesn't rely on the .NET framework. Additionally, all previous versions
of VB Decompiler up to v8.5 can be run on Windows 95 without any issues.
All prior years saw us only decompile .NET structures and disassemble MS IL.
Starting in 2023 with version 12.1, VB Decompiler supports the decompilation
of .NET code! This code can be written in Visual C# .NET, Visual Basic .NET
or any other CIL-compatible language.
It could be x86 code or x64 code, managed or unmanaged - VB Decompiler handles it all!
And just like in the early versions, VB Decompiler doesn't use the .NET framework
within its decompiling process. You can decompile .NET code on a PC without having
the .NET framework installed!
This is the first version of C# decompiling and some features aren't yet supported.
Already supported are Try...Catch exceptions, Case statements, initializing arrays
on the stack, and numerous MS IL opcodes. Loop recognition isn't currently
supported either, appearing as "if...then" blocks instead. Support for C# wrappers
in Visual C .NET for fast array initialization is also not yet available
but will be added in future updates.
- Significant improvements have been made to Visual Basic obfuscation with
a lot of code refactored for better performance
- Compatibility fixes with Chinese Windows locale (different processing
of non-unicode characters)
- Decompile "type" of the handler for the Small SEH frames added (.NET)
- Click to select any address in the Decompiler tab, then open the Disassembler tab;
VB Decompiler will navigate to and highlight that address.
- Click on any address within a comment "Referenced from" in a code to
highlight that address
- Support for the "Add HEX dump" option has been added to MS IL .NET disassembler (.NET)
- Additions to the Chinese Simplified UI translation by fairycn
- BugFix: decoding branches back (.NET)
- BugFix: Windows XP compatibility fixes
VB Decompiler v12 has been released (February 8, 2023)
What's new in this version:
- Compatibility with Mac OS on M1 processors via Parallels
- Faster decompiler loading speed across all licenses
- New Dark Theme and support for custom themes based on dark and light colors.
Many controls and application code have been refactored, rewritten, and
optimized to support this new feature, along with the addition of
numerous color scheme parameters. Fonts (family and size) can now be
changed separately for Solution Explorer, Decompiler, and HEX Editor.
Additionally, users can customize colors for all parts of Highlighting
Code and all parts of HEX Editor. The Color Scheme topic in
English documentation has been updated with information on
how to create your own color theme.
- Users can now select multiple Font Families for each part of the UI control
in a color schemes configuration file, supporting Windows,
Linux, and Mac systems where installed fonts may differ.
- Dark Theme support is provided for Parallels in Mac OS and Wine on Linux systems.
Although there's an issue with menu refreshes in Steam Deck console when using
Dark Theme (tested on Wine, not Proton), other features work fine.
- Approximately 50 icons have been redrawn to support
smooth transparent rendering in the Dark Theme
- A new .NET strings mangler and demangler has been added to support
special characters in code and editing in String References (.NET)
- Duplicate entries will no longer be shown in "String References" if they are
used at the same method, but will still be displayed when methods differ
- New parsing algorithms for arguments of the __vbaVarLateMemSt and
__vbaLateIdSt msvbvmXX.dll APIs have been implemented to support
class properties with reverse order Dispatch IDs
- The Tracer for P-Code compiled programs has seen significant improvements
including showing variables and a list of previously
decompiled code (Tracing features)
- Translations are now supported in Native Code and P-Code Tracers
if translations exist for your language within a "lang"
subfolder of the VB Decompiler installation folder (Tracing features)

VB Decompiler v2.7 has been released (Sept. 25, 2006)
What's new in this version:
This decompiler version contains major modifications. Now you can
decompile even a 10-megabyte EXE file in only 5-10 seconds thanks
to on-the-fly decompilation technology. Now, if you select the
"Fast decompilation" checkbox in the options, the decompiler will
decompile not the entire file, but only the tree of functions. Functions
will be decompiled transparently for you when you access them, so you
can start analyzing the file at once. Of course, the decompiler will
decompile the rest of the file when you save the project, but it's better
anyway as it is much more important to start faster than to save the
project faster. Let me remind you that you might as well disable this
option. You will also find the "Cache decompiled code" checkbox in the
options. It is used to decompile a function only once; when you access it
later, it will take code from the internal structures of the decompiler. Do not
enable this option if you want to use different on-the-fly decompilation methods
via the "Compile stack parameters" and "Procedure analyzer and optimizer"
checkboxes.
