When using the ABBYY engine within Umango you may see the following error message:
Retrieving the COM class factory for component with CLSID {100020D3-0000-1056-976E-008048D53AE3} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
This relates to the permissions of the user account attempting to load the ABBYY Outproc service (the Umango Windows service logon account) not being sufficient to load the process. To resolve this, follow the steps below:
Note that on a 64-bit operating system the registered DCOM-application is available in the 32-bit MMC console, which can be run using the following command line: "mmc comexp.msc /32".
Also ensure that the service logon account has read permissions for the registry key below:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{12002016-0000-1056-976E-008048D53AE3}
