Silently install ArcGIS Server patches

Summary

Patches for ArcGIS Server can be installed silently in environments where a user interface is not available. Installing silently is also useful when using automated processes.

Procedure

1. Download the necessary patch from the Esri Support Downloads page.
2. Launch Windows Command Prompt.
3. Enter the following command to install the patch:

msiexec.exe /quiet /passive /p <location of downloaded patch file>

Note:
The msiexec.exe command is a Windows installer, and is used to execute .msi files. The default path for this is C:\Windows\System32. Using the 'msiexec.exe -h' command in Windows Command Prompt displays the different parameters associated with msiexec.exe and their meaning.

Note:
The '/p' parameter is not displayed when using the 'msiexec.exe -h' command. This parameter indicates a patch is being applied.
