There have been several times I’ve attempted to install Failover Clustering Tools on a server and received the following error: “Object reference not set to an instance of an object”
Here are the steps I’ve taken in the past to correct this:
- Open PowerShell with “Run as Administrator”
- Run this command:
1Install-WindowsFeature -Name Failover-Clustering –IncludeManagementTools
