ABBYY ocr not working

Hello guys,

I have recently installed ABBYY FR11 engine with key to use it in uipath but unfortunately I keep getting this below error. Any help on this issue would be really appreciated.

Main has thrown an exception

Source: Abbyy OCR

Message: Error performing OCR: AbbyyErrorLoadEngine

Exception Type: Exception

Hi @jamnanin,

For Abby OCR activity to work, you need to install ABBYY FineReader Engine and purchase a license for it.

It’s not Free


@arivu96 yes i have purchased a license and registered it too.

do you have the x86 engine installed?

I have installed the 64 bit version. @Gabriel_Tatu

Thats not gonna work, install x86 please.

Installing it gives me an error saying that the dll is already in use. how can i get rid of this error? @Gabriel_Tatu

I m not sure what error you are having, can you give more details?

Thanks @Gabriel_Tatu I managed to get it working.

I am still unable to get an option for “Abbyy OCR” in the scraping method drop down. i have to manually change it in the sequence. Is there a way to get the OCR in the drop down?

Abbyy does not work like that, it is used for scraping documents - pdf, images etc as a standalone engine. It is not available in the Screen scraping wizard.

Sure, Thank you for the help @Gabriel_Tatu

Hello guys,

How do you know if what you installed is a x86 or x64 version?
i am facing the same error “Error performing OCR: AbbyyErrorLoadEngine”.
Please help.

Here are the steps involved - had to try this numerous times going back and forth between UiPath and Abbyy separately. The trial license was installed on my machine (not network)

Abbyy FineReader Engine Local:

  1. Download link:
  2. Open elevated cmd in the folder where you extracted the archive and run: Setup.exe /qb /v INSTALLDIR=“C:\Abbyy\FR11” SN=serialkey ARCH=x86 LICENSESRV=Yes
  3. Open location C:\Abbyy\FR11\Bin and execute LicenseManager.exe – key in Serial Key in the License Manager window and save.
  4. In UiPath Studio - properties pane of Abbyy OCR, change the Fine reader version to FineReaderEngine11

Few notes -

  1. UiPath provided trial run time license of Abbyy FineReader 11 (not 12)
  2. Also Abbyy run time license is required (not developers license)
  3. Abbyy Installation folder C:\Abbyy\FR11 - is very important - do not deviate

Hope this helps
