Typo in the PowerShell cmd shown at the end of IPAM provisioning wizard
On the completion page of the "Provisioning IPAM" wizard, there is a typo in the PowerShell command used to create the GPOs. It reads "Invoke-IpamGpoProvisiong".
Also, I would like to suggest that the wizard detect conflicting roles and features before IPAM is installed. For example, if the machine you're installing IPAM on is a domain controller or a DHCP server, it will warn you of these issues before you install the IPAM feature.
