Products

Issue/Introduction

Symptoms:

• In the vRA installation wizard, you cannot get past the prerequisites steps even when using the "fix" button.
• You may receive errors similar to:

Unable to execute check: No IIS (7.0 or above) installed.

• This issue has only been identified in Windows Server 2019 deployments.

Environment

VMware vRealize Automation 7.6.x

Resolution

VMware is aware of this issue.

A resolution for this issue is being evaluated for inclusion in a future release.

Workaround:

• To work around this issue you will want to install the IIS components on all web nodes and then the vRealize Automation Management Agent.  
• You can install IIS via Powershell on the Windows 2019 instance using the command:

Install-WindowsFeature -name Web-Server -IncludeManagementTools
Install-WindowsFeature -name Web-Webserver,Web-Http-Redirect,Web-Mgmt-Console, web-metabase

• Once this is completed and the vRealize Automation Management Agent is installed, installation should be able to move forward.
