Just noticed that you used incorrect path on both occasions (takeown and certutil).
The Path I posted.
C:\Windows\WinSxS\amd64_netfx4-mscordbi_dll_b03f5f7f11d50a3a_4.0.15912.120_none_0070c05b73a8c01b\mscordbi.dll
The path you typed:
C:\Windows\WinSxS\amd64_netfx4-mscordbi_dll_b03f5f7f11d50a3a_4.0.15805.607_none_00509408c185b750\mscordbi.dll
Where did you get that from? I did not post that path.
So, run the takeown and certutil commands *exactly* as I posted. Delete the incorrect screenshots to avoid confusion.
