Commented Unassigned: Getting error when re-running AutoSPInstaller to install some other services [22214]

Hi,
I am getting the following error when re-running the latest version of AutoSPInstaller 2nd time.
Any ideas?
- Granting rights to Metadata Service Application:

'Microsoft.SharePoint.PowerShell.SPServiceApplicationPipeBind' required by parameter 'Identity'. Specified method is
not supported.

Please delete this issue. Just found out the code was crashing because I had created a 2nd Managed Metadata Service.
