0x8002801c error when trying to unregister scrrun.dll Win2008 R2 64bit

For the DoD STIGS, they want you to unregister the File System Component and their steps are to unregister scrrun.dll

I'm on Win2008 R2, SP1, 64bit.  I open a command prompt with 'run as administrator', I try

regsvr32.exe scrrun.dll /u

or

regsvr32.exe c:\windows\system32\scrrun.dll

And I've tried with the regsvr32.exe that is in c:\windows\syswow64 

Everytime I get the same error 'The module 'c:\windows\system32\scrrun.dll' was loaded, but the call to DllUnregisterServer failed with error code 0x8002801c.'

Hits with google infer not running as administrator (but I am) or registry permissions (didn't see anything glaring with Procmon).  This is a vanilla box except a few minor adds like IIS, SQL Server 2008 R2.

What can I do to be able to conform to this STIG on Win2008 R2 64bit?
