Unable to install ArcGIS Pro silently

Description

ArcGIS Pro can be installed silently by running the setup using the Windows Installer command line parameters without a user interface (UI). In some instances, attempting to authorize the installation of ArcGIS Pro silently using the command line parameters does not work. The Software Authorization Wizard window opens and requires manual input to continue the license authorization.

Cause

The silent installation is unsuccessful because the license file referenced by the ArcGIS Pro silent install command is incomplete. A license file must include the required user information elements, including the 'Your' lines, as shown below.

Your Organization= <Please choose a category>
Your Industry= <Please choose a category>
Yourself= <Please choose a category>

Note:
The license file created in My Esri does not include the three elements above. My Esri does not provide the ability to add these elements at the moment.

Solution or Workaround

Note:
Esri recommends storing the license file on the same machine where the installation is performed.

To resolve the issue, follow the steps provided. Create a backup of the license file, and manually type the missing elements in the file.

1. Open the license file using a text editor, and make a backup copy of the license file.
2. Manually type the missing lines below the user information and before the version information. A sample text of the license file is shown below.
