“Access Denied” errors during ABBYY FlexiCapture operation


Users may encounter the following “Access Denied” errors when working with FlexiCapture 12 components:

  • When launching the Processing Station from the Processing Server Monitor, the Processing Station stops and the following message appears: “Access Denied.”


The above errors may occur if remote procedure calls of unauthenticated clients are not allowed.
