* **Checking for Updates:**

1. **Open the Blender Launcher:** If you have it installed it can be found in the start menu by searching for ‘Blender Launcher’.
2. **The Launcher interface:** The launcher will appear and list all the Blender installations that it can find on your system. It displays version numbers, and when available, update buttons.
3. **Update Button:** If an update is available for one of your Blender installations, an ‘Update’ button will be visible next to the entry in the list. Click on it to start the update.
4. **Follow the instructions:** The launcher will automatically download and install the latest version, typically without needing any interaction. You might be asked for administrator permission.
5. **Restart Blender:** After the update is complete, restart Blender to apply the changes. The update button should dissapear.

* **Installing the Blender Launcher (If you don’t have it):**

1. **Download the Installer:** Go to the official Blender website ([https://www.blender.org/](https://www.blender.org/)) and navigate to the ‘Download’ section.
2. **Choose the correct version:** Select the Windows version of Blender, the launcher is packaged alongside. If you have a specific architecture requirement (extremely rare, but possible) you can choose a specific installer. Otherwise the standard installer is usually fine.
3. **Run the Installer:** Run the downloaded installer file (.exe). You will need Administrator rights to install.
4. **Follow the on-screen prompts:** Accept the license agreement and choose an installation location. Make sure to check the box that says ‘Install Blender Launcher’.
5. **Finish the installation:** Once the installation is complete, the Blender Launcher will be available in your start menu.

**2. Using the Built-in Updater (macOS and Linux):**

Blender for macOS and Linux has a built-in updater that simplifies the process. The update process is very similar.

* **Checking for Updates:**

1. **Open Blender:** Launch Blender on your macOS or Linux system.
2. **Go to the ‘Help’ Menu:** In the top menu bar, click on ‘Help’.
3. **Select ‘Check for Updates…’:** In the help menu, choose the ‘Check for Updates…’ option. Note: this option only appears if using an installation method that supports automatic updates, such as the .dmg package for MacOS.

* **Installation Process (Installer):**

1. **Run the Installer:** Run the downloaded installer file (.exe for Windows, .dmg for macOS). Administrator rights might be required.
2. **Follow the on-screen prompts:** Accept the license agreement, choose an installation location (it’s generally fine to use the default), and follow the instructions. Make sure the installer overwrites the previous installation by selecting the same location, or uninstalling the old installation beforehand.
3. **Finish the Installation:** Once the installation is complete, you can launch the updated Blender.

* **Installation Process (Archive):**

1. **Extract the Archive:** Extract the contents of the downloaded archive (.zip or .tar.gz) to a folder of your choice. A new folder will be created containing the Blender executable and all necessary files.
2. **Replace the Old Installation (Optional):** To update your existing Blender installation, simply replace the contents of your old Blender folder with the contents of the extracted archive. This will overwrite the old files with the new ones. You should back up your old Blender directory beforehand just in case something goes wrong.
3. **Run Blender:** Navigate to the extracted folder and run the Blender executable.

**4. Using Package Managers (Linux):**

On Linux, you can also update Blender using your system’s package manager (e.g., apt, yum, pacman). This method integrates Blender updates with your system’s overall software management.

* **Update Your Package List:**

1. **Open a Terminal:** Open a terminal window on your Linux system.
2. **Update Package List:** Run the appropriate command to update your package list. For example, on Debian/Ubuntu-based systems, you would use `sudo apt update`. On Fedora/CentOS/RHEL, you would use `sudo yum update`. On Arch Linux, you would use `sudo pacman -Syu`.

* **Update Blender:**

1. **Run the Update Command:** Run the appropriate command to update Blender. For example, on Debian/Ubuntu-based systems, you would use `sudo apt upgrade blender`. On Fedora/CentOS/RHEL, you would use `sudo yum update blender`. On Arch Linux, you would use `sudo pacman -S blender`.
2. **Confirm the Installation:** Follow the on-screen prompts to confirm the installation and download the updated packages.

**5. Updating Experimental Builds (Blender Daily Builds):**

If you’re interested in testing the latest features and bug fixes before they are released in stable versions, you can download and use Blender’s experimental builds (also known as daily builds or alpha/beta versions). These builds are updated frequently and provide access to the cutting edge of Blender development.

* **Download Experimental Builds:**

1. **Go to the Blender Builds Website:** Navigate to the Blender builds website: [https://builder.blender.org/download/](https://builder.blender.org/download/)
2. **Choose Your Operating System:** Select the appropriate version for your operating system.
3. **Download the Build:** Download the latest build. These are typically provided as archives (e.g., .zip or .tar.gz files). The naming convention usually includes the date the build was created.

* **Installation Process (Archive):**

1. **Extract the Archive:** Extract the contents of the downloaded archive to a folder of your choice. This will create a new folder containing the Blender executable and all necessary files.
2. **Run Blender:** Navigate to the extracted folder and run the Blender executable. Experimental builds do *not* usually get installed into the same location as a stable build. They are designed to run from their extracted directory.

**Important Considerations for Experimental Builds:**

* **Instability:** Experimental builds are by definition unstable and may contain bugs or unfinished features. Use them with caution and avoid using them for critical projects.
* **Data Loss:** There is a higher risk of data loss when using experimental builds. Always back up your work before opening your files in an experimental version of Blender.
* **No Automatic Updates:** Experimental builds typically do not have automatic update features. You’ll need to manually download and extract new builds to stay up-to-date.
* **Report Bugs:** If you encounter any bugs or issues while using an experimental build, report them to the Blender development team. This helps them improve the software and fix problems before the stable release.

General Tips for Updating Blender

Here are some general tips to keep in mind when updating Blender:

* **Back Up Your Configuration:** Before updating, it’s a good practice to back up your Blender configuration files (located in your Blender preference directory). This allows you to restore your settings if something goes wrong during the update process. The location depends on the OS; a quick google search can find it for your system.
* **Test the New Version:** After updating, take some time to test the new version and ensure that everything is working as expected. Open some of your existing projects and check for any compatibility issues or unexpected behavior.
* **Read the Release Notes:** Always read the release notes for each new version of Blender. This will provide you with information about new features, bug fixes, and any important changes that may affect your workflow. The release notes can be found on the blender.org website in the ‘releases’ section under the ‘development’ section. You can also usually find them by searching online for ‘Blender [version number] release notes’.
* **Be Careful with Add-ons:** Add-ons may not always be compatible with newer versions of Blender. After updating, check if your add-ons are working correctly and update them if necessary. Check the website that you downloaded the addons from. If it is a built in addon, then simply disable it, restart blender, and re-enable it. This will often update the addon.
* **Consider Multiple Installations:** You can have multiple versions of Blender installed on your system simultaneously. This is useful if you need to maintain compatibility with older projects or if you want to test new features without affecting your stable workflow. The Blender Launcher makes this easier to manage on Windows.

Troubleshooting Common Update Issues

Here are some common issues you might encounter when updating Blender and how to resolve them:

* **Installation Errors:** If you encounter errors during the installation process, make sure you have sufficient permissions to install software on your system. Try running the installer as an administrator (Windows) or using `sudo` (Linux). If using the archive version, make sure the files are not read-only.
* **Compatibility Issues:** If your existing projects are not working correctly in the updated version of Blender, try opening them in the previous version to identify the source of the problem. You may need to adjust your settings or update your add-ons.
* **Add-on Problems:** If your add-ons are not working after the update, check for updates on the add-on’s website or try reinstalling them. If the add-on is no longer supported, you may need to find an alternative.
* **Crashing or Freezing:** If Blender crashes or freezes after the update, try resetting your Blender preferences to the default settings. You can do this by deleting or renaming your Blender configuration directory.
* **Missing Files:** If files seem to be missing after an update, ensure that the installation completed successfully and that all necessary files were extracted to the correct location. If you used the automatic update feature, try manually downloading and installing the latest version.
