Powershell Get-ProcessMitigation -name Fails

We are trying to implement the Win 10 1809 STIG. Several of the checks in the STIG use Get-ProcessMitigation -Name PROGRAM.  Several checks are failing due to the PS command error below:

Get-ProcessMitigation -Name Acrobat.exe
Get-ProcessMitigation : Requested registry access is not allowed.
At line:1 char:1
+ Get-ProcessMitigation -Name Acrobat.exe
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Get-ProcessMitigation], SecurityException
    + FullyQualifiedErrorId : System.Security.SecurityException,Microsoft.Samples.PowerShell.Commands.GetProcessMitigationCommand

However, the following runs fine:

Get-ItemProperty -path 'HKLM:\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\Acrobat.exe'

DisableExceptionChainValidation : 0
MitigationOptions               : {1, 1, 33, 0...}
MitigationAuditOptions          : {0, 0, 0, 0...}
PSPath                          : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\Acrobat.exe
PSParentPath                    : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
PSChildName                     : Acrobat.exe
PSDrive                         : HKLM
PSProvider                      : Microsoft.PowerShell.Core\Registry

Select allOpen in new window

Get-ProcessMitigation -system also runs fine.  Get-ProcessMitigation without the -name is suppose to return all the program values, however that has the same registry error.  We are having a hard time trying to figure out how to fix this so we can get accurate results.
