Commented Unassigned: Get-EnterprisePKIHealthStatus Error [86]

When I run Get-Ca | Get-EnterprisePKIHealthStatus -Debug -Verbose I receive the attached error. I'm running this command from an elevated PowerShell session on Windows 8.1 Enterprise. My PKI consists of an offline root ca and an enterprise sub-ca
Comments: Hello. I can confirm that all modifications: replacing PSPKI.zip, replacing PKI.Core.dll and replacing 463 string in Get-EnterprisePKIHealthStatus.ps1 fixed the issue. Thanks.
