This article applies to:

  • Acronis Backup & Recovery 11.5


  1. Acronis Backup & Recovery 11.5 Advanced version is installed on a Windows machine;
  2. An attempt to connect to a local machine from Acronis Management Console or to add a local machine to the Acronis Management Server fails with an error similar to:

    Code: 13.238.288(0x00CA0010)
    LineInfo: 0xEC81F6265C057C51; 

    Module: mms_vs_32256 
    Message: The requested license holder cannot be found


On the affected system a corresponding registry information in credential storage is broken.


The issue is fixed in build 37613 and later builds.

Workaround: to exclude any possible issues after this procedure described below, export the key HKEY_USERS\"MMS_USER_ID"\Software\Acronis\CredStorage\ registry folder before following the steps. Where MMS_USER_ID is the user ID under which the Managed Machine Service (MMS) is running (i.e. S-2-5-21-322223-3065465924-3880868183-2001).

The user SID may be identified with the following command in the command line (Start -Run -> cmd):

of a local user
wmic useraccount where name='username' get sid

of the currently logged in user
wmic useraccount where name='%username%' get sid

of the currently logged in domain user
whoami /user

of the local administrator of the computer
wmic useraccount where (name='administrator' and domain='%computername%') get name,sid

of the domain administrator
wmic useraccount where (name='administrator' and domain='%userdomain%') get name,sid

Locate your MMS user in the output list to find the corresponding user SID.

Once the key is exported, follow the below instructions for the corresponding OS family:
