Resolving Error 1406 when installing Portal for ArcGIS

We are attempting to install Portal for ArcGIS, and we encountered:

Error 1406. Could not write value Installer to key \Software\ESRI\Portal for ArcGIS.  Verify that you have sufficient Access to that key, or contact your support personnel. 

I found an old posting from Esri about this issue related to installing an old version of ArcCatalog, and it suggests that it can be resolved by disabling our antivirus software during the installation--and we would rather not attempt that.


Has anyone else encountered this error? And what is the solution. I'm not entirely sure what folder I need access to.


 We are using Chef, but the same error comes up when manually installing, as well.
