If you are running the current major release of Grapher, minor updates are available for free by clicking the File | Online | Check for Update command within Grapher. To use this command, we recommend running the program as administrator in order to ensure that the update process will be given permission to complete the download and installation.  To run Grapher as administrator, right click the Grapher desktop icon or application EXE and click Run as administrator.  

If you are running a concurrent-use license, please see the knowledge base article: How do I upgrade my concurrent-use license to the latest version if my maintenance is active? 

If you experience any problems with this command or would like to download the full version of the updated software, and you are running Grapher 4 or newer, you can log into the My Account portal on the Golden Software website, click the My Products button, and then click on your serial number/product key.  In the expanded license information, click Download Grapher <version> installer.

If you are using Grapher 3 or earlier, please email your registered Grapher serial number to graphersupport@goldensoftware.com. Once your serial number is verified, we will send you download instructions for the most recent version of your software. To determine your serial number, click the Help | About Grapher command. The serial number is listed in the dialog.

Version information can be found on the Version History page. 

If you are running a previous version of Grapher and are interested in upgrading to the current version, additional information about this can be found in the articles How Do I Upgrade To The Latest Version If My Maintenance Is Active? and How Do I Purchase An Upgrade?.
