Windbg for memory analysis using mimikatz ERROR

Question

I'm using windbg version 6.12 and using mimilib.dll for debugging memory. All works fine until I get following output on UI

0:000> !mimikatz

DPAPI Backup keys
=================

Current prefered key:       

Compatibility prefered key: 

SekurLSA
========
[ERROR] [CRYPTO] Acquire keys

note: the memory dmp is of lsass

Is this anything to do with symbol or respective dll /system32? Kindly suggest.

I was using WinDbg x86 where x64 was required.
