Unable to load document definition from: *.fcdot


For a week I have been struggling with an error in UiPath Studio for the activity IntelligentOCR of the fcdot file:


Source: Process Document

Message: Unable to load document definition from: Sample3EXP.fcdot

Exception Type: System.ArgumentException

An ExceptionDetail, possibly created by IncludeExceptionDetailInFaults = true, whose value is:

System.ArgumentException: Unable to load document definition from: Sample3EXP.fcdot

   at UiPath.IntelligentOCR.Activities.FC.Scope.OnFaulted (NativeActivityFaultContext faultContext, Exception exception, ActivityInstance source)

   at System.Activities.Runtime.FaultCallbackWrapper.Invoke (NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)

   at System.Activities.Runtime.FaultCallbackWrapper.FaultWorkItem.Execute (ActivityExecutor executor, BookmarkManager bookmarkManager)


There is a problem with the creation of the FCDOT file (arguments) in ABBY FlexiCapture 12. The example FCDOT from the internet works correctly, the ones published from my computer do not work :( The Definition document is correct and the tests pass well in ABBY FlexiCapture. I'm asking here because not many people have such a problem on the UiPATH forum. Has anyone encountered this problem?

    Hello Daniel,

    Exactly the same situation here. I've been on it for days, only 1 result: dead end.

    Despite my efforts, a perfectly valid project using a Flexilayout afl -> Flexicapture 12 Document Definition does not Publish a working *fcdot file which can be processed by UiPath.

    Moreover, comparing the locally generated fcdot after publishing with an *.fcdot that actually works in UiPath, the difference in size is from 400 kb *faulty one* to 3mb *the working one*.


    Looking forward to solve this issue ASAP, please don't forget to reply to the post if you find a solution.

    Hi Godo,

    What do you mean by the fact that your file locally generated works?


    In our case, it does not work under UiPath Studio, the generated FCDOT file, in different configurations - even simple with one field. 

    I'm sure that the size of the FCDOT file doesn't matter. The FCDOT file works with size 100kb, 2mb or bigger.

    The size depends on how many batch test files you attach.

    Hi All,

    Problem solved.

    The error is due to the incompatibility of the application version: ABBYY FlexiCapture and ABBYYFlexiCapture Engine.
