"Could not load file or assembly "Microsoft.Web.Administration"" error when manually running IaaS installer on a Windows node

Products

• VMware Aria Suite

Issue/Introduction

Symptoms:

• When running the vRealize Automation 7.6 IaaS component installer on a Windows node where IIS Management Console is not installed/enabled.
• The prerequisite check step fails, you see the error:

"Could not load file or assembly "Microsoft.Web.Administration""

Environment

VMware vRealize Automation 7.x

Cause

The prerequsite checker attempts to get the HTTPS port setting from IIS and fails if it is not installed/enabled.

Resolution

Currently, there is no resolution.

Workaround:
After starting the manual IaaS installer for the first time, it creates a configuration file with the same name as itself, in the same directory.

To workaround this issue:

1. Open this file and add this entry in the <appsettings> section:

<add key="PreReqChecker.Default.IISPort" value="443" />

 

Note: For non-default port configuration - use the custom port instead of "443".

2. Restart the installer for the changes in the configuration file to take effect.
