Source Insight Downloads

This is the place to download the latest Source Insight updates, as well as sample macros, and custom language plug-ins.

Free point-releases are made from time to time to fix bugs and add features. In order to use the updates, you must have a valid Source Insight serial number, or run it in Trial mode.

The updates contain a full installation of Source Insight. They are not patch files, so you do not need to have Source Insight installed on your machine already.

Source Insight 4 - Latest Version

Version 4.0.0141 - February 7, 2025

This requires a valid version 4.x license, OR you can run this in Trial mode for up to 30 days.

Fix: C/C++/C#: Some class or struct member names used inside initializers where not correctly recognized.

Fix: Resizing docked panel windows didn't resize correctly if the system's Window Performance settings for "Show window contents while dragging" was disabled. This could also affect Remote Desktop connections if the corresponding option was disabled for remote connections.

Fix: Using the "Set all Panel Fonts and Colors" feature in Options > Preferences > Font & Colors did not save the Symbol window pane font settings in the configuration file so they would not persist in subsequent sessions.

Fix: Code collapsing bug when collapsing an 'else' block that starts on the same line as the closing { } block. For example:
} else { ...

Fix: Opening a new project did not refresh the File > Recent File menu right away, even though the recent-file-list is stored as part of each project.

Fix: Formatting of text with style properties using capitalization changes or expanded spaces was sometimes drawn incorrectly.

Fix: C++ function signature types are now recognized. For example:

typedef int some_function(int foo) noexcept;

Change: You can now specify the folder where log files are stored by selecting Options > Preferences > Folders. You can also disable logging completely by selecting Options > Preferences > General > Logging and de-selecting the option "Output to log file". Furthermore, the logging preferences are now stored in the Windows Registry and apply as soon as Source Insight starts up. Previously the logging was turned on by default until logging preferences were loaded later from the configuration file. 

Change: Removed shaded font text on panel titles.

New: Big-Endian UTF-16 encoding with BOM (Byte Order Mark) is now supported. If you open a file without the BOM in big-endian format, Source Insight will not be able to automatically decode the file. In this case, use File > Open As Encoding and select "UTF-16 BE no BOM".

Source Insight 3.5 - Latest Version

Version 3.5.0086 - October 17, 2019

This requires a valid version 3.x license.

Version 3.50.0086 - October 17, 2019

Small changes to dialog font handling, and edit text control for compatibility. 

Updated code signing certificate.

Version 3.50.0083 - June 7, 2016

Fix: Macro functions GetSymbolLocation and GetSymbolLocationEx were failing to find project files when the given symbol parameter was the name of a file.

Version 3.50.0082 - March 11, 2016

Fix: Display bugs fixed for Windows 10, high DPI displays, and using Windows magnification greater than 100%. In particular, resizing or moving docked windows did not draw correctly in those situations.

Fix: C/C++ #include statements: The Jump To Definition command would not open the file in the include statement if the file was in a subdirectory. For example: #include "subdirheader.h". Now the path in the include statement is evaluated relative to the project source root directory.

Fix: Relation window was not showing function call trees correctly for Visual Basic and Basic.

Fix: Replace command: the "Whole File" option setting is now preserved after pressing the Replace button.
