How to Check Your Paint.NET Version

Installing third-party plugins in Paint.NET requires running a compatible version of the software, as newer effects and file type add-ons frequently rely on the latest application architecture. This guide provides a straightforward method to quickly check your current Paint.NET version number and system architecture directly from the application interface to ensure smooth plugin installation.

  1. Launch Paint.NET.
  2. Click the Gear icon (Settings) located in the upper-right corner of the window, next to the minimize button.
  3. In the Settings window that appears, select the About tab from the left-hand navigation panel.
  4. Your full version details will appear at the top of the pane (for example, Paint.NET v5.0.13), along with whether you are running the 64-bit (x64) or ARM64 build.

Method 2: The Help Menu

  1. Launch Paint.NET.
  2. Click the Help button (represented by a question mark icon or the word "Help") on the top menu bar.
  3. Select About from the drop-down menu.
  4. A dialog box will display the application name, version number, build type, and copyright information.

Why Version Matching Matters for Plugins

  • Minimum Version Requirements: Many modern plugins are developed targeting Paint.NET 5.0 or newer and will fail to load on Paint.NET 4.x or 3.5.x.
  • Architecture Mismatch: Most current releases run natively on 64-bit (x64/ARM64). Installing a legacy 32-bit plugin into a 64-bit installation can cause the plugin to be ignored or generate errors during startup.
  • .NET Runtime Dependencies: Newer releases depend on modern .NET runtimes (such as .NET 7 or .NET 8). Verifying your build ensures that both your application and any prerequisite runtimes match the requirements specified by the plugin developer.
