Hello,
For you guys who are still having this issue with Abbyy FlexiCapture in UiPath. This issue is caused by failing to register one (or more) of the necessary DLLs of Abbyy FlexiCapture Engine. The cause behind it could be a corrupted installation package or even an antivirus such as Trend Micro which blocks the registration tool regsvr32.exe. If you have this antivirus installed, uninstall Abbyy FlexiCapture Engine, disable the real-time protection of the antivirus, then install Abbyy FlexiCapture Engine. You can then restore the real-time protection of your antivirus. Run the workflow in UiPath, check if the issue is solved.
Hope that helps.
Best regards,
Kenan
