I have a corrupted install of Symantec Endpoint Protection on one of my Windows Server 2012R2 servers and I am trying to manually remove the software (following Symantec's guide). Two of the keys (HKLM\Software\Symantec\Symantec Endpoint Protection\CurrentVersion and HKLM\Software\Wow6432Node\Symantec\Symantec Endpoint Protection\CurrentVersion) I need to delete are giving me the following error as soon as I try and access either key:

CurrentVersion cannot be opened.
An error is preventing this key from being opened.
Details: The system cannot find the file specified.

I have tried removing it in safe mode. I have tried using the RegDelNull utility from SysInternals. I have tried deleting it from the command line (REG /DELETE) and I have tried deleting the parent key. None of these things worked. It is not a permission issue because if I try and go in to the permissions for this key I just get a red X and the message "The requested security information is either unavailable or can't be displayed."

How can I remove these keys?
