IntelligentOCR Process Document error UiPath and ABBYY FlexiCapture

Hi all,

I have issue with IntelligentOCR scope. When i try to run simple workflow there is an error:

Source: Process Document

Message: Error converting FlexiCapture document

Exception Type: System.Exception

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.Exception: Error converting FlexiCapture document ----> System.InvalidCastException: Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘FCEngine.ICustomStorage’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{C0002062-0000-48FF-9197-57B7554849BA}’ failed due to the following error: Taki interfejs nie jest obsługiwany.

Thanks for help,


@Bogdan10g Just try this

  1. Create one new project and delete the xaml file
  2. Copy your xaml(exception which you are getting now) and paste into the new project folder

Hi @Bogdan10g

Hi @indra

Unfortunately that does not help.



Hi @AshwinS2

I read this topic before I created my own. I could not find there anything about error which I have.
