Keep in mind that the OCR license for RPA Express 2.2.3 and earlier versions expires today, May 15.
If you get the following exception
Error executing OcrAction
Caused by: org.openqa.selenium.WebDriverException: java.lang.ClassNotFoundException: com.workfusion.desktop.driver.ocr.impl.OcrException cannot be found by com.workfusion.studio.dependencies.rpa-api_220.127.116.11
you need to update to the new RPA Express version - 2.3.0, to be able to use OCR.
