Source Insight – version 4.0.0148
Source Insight
Version 4.0.0148 - October 2, 2025
Fix: Changes to font metric handling to improve appearance for some fonts.
Recent Update 4.0.0146:
New: Line Spacing: You can set the line spacing by selecting Options > Preferences > Windows.
This replaces the old setting for "Smaller line heights" found in Options > Preferences > Display > Spacing.
Change: #pragma region items now show in the symbol pane on the left so that they can be collapsed.
Change: Miscellaneous UI improvements and updated scroll bars. The horizontal scrollbar now only appears if needed.
Change: Using the -license-file option to install a license now runs to install the license and then exits immediately. This is useful for automated installs in scripts. The sourceinsight4.exe program returns a non-zero exit code if errors, and displays any error messages in the console if it was invoked from the command shell.
Change: Custom Language properties: added options for numbers in the formats: nnnb binary, nnnx hex, 0bnnn binary, and 0onnn octal.
Fix: C++: Raw strings are handled correctly.
Fix: C++: Resolving auto type expression was not correct if a subscript was used.
Fix: Parser could crash when expanding some token macros on long lines.
Fix: C/C++: static_assert(...) is parsed correctly.
Fix: C/C++: several standard types, such as uint_fast8_t, were added to the default syntax highlighting.
Fix: Bookmarks: Editing a file could cause bookmarks to shift to point to a different file or position and seem to disappear.
Fix: Symbol Pane on left side could become unresponsive for a few seconds in some situations.
Fix: Improved font handling uses more accurate font metrics.

Source Insight – version 4.0.0141
Source Insight
Version 4.0.0141 - February 7, 2025
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".
9/9/2025: Re-signed with renewed code signing certificate.
Source Insight – version 4.0.0139
Source Insight
Version 4.0.0139 - June 26, 2024
Fix: Screen resolution changes could cause the panel layout to get corrupted.
Fix: Several bugs fixes and improvements to the window panel docking and layout system.
Fix: Crash in C++ template type resolution could happen on particular source files. The crash could happen just scrolling through a file, or if the Relation window updated.
Fix: Window menu numeric shortcut keys were not consistent.
Fix: Relation Window Graph: Copy to Clipboard was not copying the whole graph background color if the whole graph was not visible in the window.
Fix: ANSI C: Removed some incorrect keywords and updated syntax keywords lists. It could cause some incorrect symbol parsing.
Change: Long project paths on the Project > Recent Projects menu are now displayed in a format with the project name first, followed by the path.
Change: Context Window: added Line Numbers menu item to right-click context menu.
Change: Context Window: Can now show outlining controls for code collapsing. You can enable or disable this by right-clicking on the Context Window and toggling the Show Outlining menu item.
Change: You can prevent a floating window from docking while dragging it by holding its position for a couple seconds before releasing the mouse button. Also, as before, you can prevent it from docking by holding the CTRL key down.
Importing v3.x Projects and Settings
Source Insight version 4 can import v3.x projects and v3.x configuration settings.
To import a project, select Project > Open Project. Click the Browse... button to navigate to the v3.x project file that has the .PR extension. The v3.x projects are usually stored in "Documents\Source Insight\Projects". Open the .PR file and Source Insight will import the project into a new version 4.0 project. The old v3.x project will remain unchanged.
To import version 3.x configuration settings, select Options > Load Configuration and navigate to the version 3.x settings folder and open the file with a .CF3 extension. It is usually in "Documents\Source Insight\Settings". The Import dialog will appear, which lets you choose which items from the configuration you would like to import.
Your existing configuration will be automatically backed up. You can use Options > Load Configuration to re-load the backup version if you need to.
Automated Installation and Licensing
Silent Installation
For versions starting 4.0.0137 and newer:
Source Insight can be installed silently by invoking the setup program with the /qn option. You must run this from an Administrator command prompt or process. For example, to setup version 4.0.0137, use this command:
sourceinsight40137-setup.exe /exenoui /qn
For versions 4.0.0136 and older:
Source Insight can be installed silently by invoking the setup program with the /S and /V options. For example, to setup version 4.0.0104, use this command:
sourceinsight40104-setup.exe /S /V"/qn"
Please make sure the double quotes are used exactly as shown. The /V option passes the " /qn" option to the Windows Installer (msiexec.exe). Also note that the version numbers in the setup executable will change with new releases.
License-Related Command Line Controls
New License Installation command line options were added starting in build 4.0.0104. These are designed to make automated installs easier. Care should be taken because these options will change and replace the license currently stored on the computer.
To specify a license file to import and use
sourceinsight4.exe -license-file <license-file-path>
The license file is provided by Source Dynamics for off-line (or network restricted) activation. You should copy the provided license file to a location on the user's disk or network before using this option.
To specify a license serial number to use
sourceinsight4.exe -license-serial <serial-number>
The user will still be prompted for their registration user name and email, but the serial number will be pre-populated. If a network connection exists, it will request an activation from the Source Insight license server.
To remove and deactivate an existing license
sourceinsight4.exe -reset-license
This will deactivate and delete the license on the computer. The next time Source Insight runs, it will prompt to activate the license. This option is effectively the same as running Source Insight and selecting Help > Manage License and selecting "Deactivate license". If a network connection exists, it will inform the license server that the license has been deactivated.
This will delete the license and license serial number from the computer. Be sure to record the license serial number first so it can be activated again.
Combining Setup and License Installation
Installing Source Insight and installing the license file is a 2-step process. First the setup program is run, then sourceinsight4.exe is run with an option to install the license file. For example, these two commands install Source Insight and then imports the license file:
sourceinsight40141_7081-setup.exe /exenoui /qn "C:\Program Files (x86)\Source Insight 4.0\sourceinsight4.exe" -license-file <license-file-path>
Freezing when Typing into Text Boxes
Symptom: Typing into a text box field, such as in the New Project dialog or the Search dialog, causes Source Insight to freeze.
This problem may be caused by a known system issue where typing characters may freeze on Windows with non-English as preferred input languages. This is due to a bug in the Windows IME.
Here are some external articles with workarounds:
https://www.neowin.net/news/microsoft-confirms-app-freezes-with-ime-in-windows-11-2022-update
Workaround Steps
To work around this issue in the short term, either manually switch the input mode when typing, or by following the steps below to enable compatibility mode:
- Select Windows Start, type "Settings" and select it or press enter.
- Type "Language" into the search box within Settings and select "Edit Language and Keyboard Options"
- Select the language, for example: Traditional Chinese, then click the Options button.
- Under Keyboards, select the Input method editor, then the Options button. Click General.
- In the Compatibility section, turn on Use previous version of Microsoft IME.
Note: The steps above may change with different versions of Windows. The important thing is to get to the Input Method Editor for your current language and enable the option Use previous version of <language> IME.
Source Insight Cannot See Network Drives
Symptom: Source Insight cannot see network drives that are mapped to drive letters.
This caused by a feature in Windows that blocks mapped drives in processes running with elevated privileges when the drives are mapped from a lesser privilege process.
If you are running Source Insight from an "elevated" command prompt (for example an Administrator command prompt), or you always run Source Insight as Administrator, but you are mapping the drives in Windows Explorer, then Source Insight may not be able to see the mapped drives. This is a security feature of Windows: If you map a drive using Windows Explorer, an elevated Command Prompt (or any other elevated process) will not be able to see it.
Workarounds
- Map the drive from an Administrator command prompt, using the "
NET USE ...." command. After that, any elevated process should see the mapped drives. - Run Windows Explorer in Administrator mode and then map the drives.
- Always run Source Insight from a normal (non-admin) command prompt or Windows Explorer.
