Check for and install software patches and updates

Esri periodically releases software patches and updates for all components of ArcGIS, including ArcGIS Enterprise. Email notifications are sent for each update and announced on the Patches and Service Packs page on the Esri Support website. You can also check if updates are available using a patchnotification utility installed with the software.

The patchnotification utility reports patch and update information for ArcGIS Enterprise components, server roles, and extensions. It will also display a list of installed patches and QFEs at the bottom of the dialog box. If more than one of these products are installed on the machine, update information for those products will also be reported.

To determine the full list of available patches, the patchnotification utility must have access to the following URL:


You can also download and install software patches and updates using the patchnotification utility. You can install specific patches of your choice, security patches only, or all available patches.

To download patches as appropriate, the tool requires access to these locations:



For the patchnotification utility to retrieve the patch information, the machine running it must have access to sites on the domain over https (port 443).

To check for and install updates, see the steps below.

  1. Sign in to the machine hosting ArcGIS Server.
  2. Click Start > All Programs > ArcGIS > ArcGIS Server > Check for ArcGIS Enterprise Updates. Alternatively, you can start the utility from the command line (patchnotification.bat). To start the tool in console mode, use the -c command (patchnotification.bat -c). The utility is located in the <ArcGIS Server installation directory>\tools\patchnotification directory.

    If your machine is offline or does not have direct access to the internet, an error message appears. If your machine uses a forward proxy server to access the internet, you'll need to specify the proxy server in the utility:

    1. Click the settings button at the bottom of the utility dialog box.
    2. On the Proxy Settings dialog box, select Connect through a Proxy Server.
    3. Specify the host name, port, and user credentials (if necessary) of the proxy server.
    4. Click OK to connect to the proxy server.
  3. Review the update information. If other ArcGIS Enterprise products are installed on the machine, information for those products also displays. Installed patches are available at the bottom of the dialog box. Click any link on the dialog box to obtain more information and instructions for downloading and installing the update.
  4. To apply a specific patch, click the download button beside the patch you want to install from the utility dialog box. The patch downloads automatically and the patch installation dialog box opens when the download is complete. Follow the instructions to complete patch installation. Optionally, click the Install Security Patches or Install All Patches buttons on the right side of the dialog box to apply the corresponding updates. If you're running the utility from the command line or in console mode, use -i sec to install only security patches, and -i all to apply all available patches.
  5. By default, all downloaded files will be saved and kept in the system temp location, and downloaded patch folders will never be deleted. To change either of these properties, click the settings button at the bottom of the utility and click the Install Settings tab.
    1. To change the default download location for patches, specify the new download location in the Download folder path. If you're running the utility from the command line or in console mode, use -d to specify a new download location.
    2. To specify that downloaded files and folders be deleted after a successful patch install, click the Delete patch folder menu and select Always delete after successful installs. If you're running the utility from the command line or in console mode, use -o always to delete the patch folder after each successful patch installation. By default, this setting is set to -o never.
  6. Ensure you apply the same patch or update to all machines in your ArcGIS Server site.

Click OK to close the patchnotification dialog box.
