  To get the value of machinekeys permissions run: 'icacls <systemdrive>\programdata\microsoft\crypto\rsa\machinekeys' in an elevated command prompt.

  Default permissions are:
  Everyone:(R,W)
  BUILTIN\Administrators:(F)

  If you see permissions on MachineKeys directory different than default, please follow below steps to correct permissions, delete the certificate and attempt the operation again.
  Fix permissions on MachineKeys directory.
  Using Explorer Security Properties and Advanced Security Settings on the directory, reset permissions back to the default values, remove any extra (than default) user object from the directory, and ensure that the ‘Everyone’ permissions had special access for:
  -List folder / read data
  -Read attributes
  -Read extended attributes
  -Create files / write data
  -Create folders / append data
  -Write attributes
  -Write extended attributes
  -Read permissions

  Delete all certificates with field ‘Issued To’ = "Windows Azure Service Management for Extensions" or "Windows Azure CRP Certificate Generator”.
