Read PDF with OCR - Method Not Found Error

“Read PDF With OCR: Method not found: ‘BitMiracle.Docotic.Pdf.ImageCompressionOptions BitMiracle.Docotic.Pdf.ImageCompressionOptions.CreateTiff()’.”

I have tried to un-install and reinstall the UiPath PDF activities package and I have the following activities packages installed:

Can you try changing the version of package and check if it works

Cheers

@Priisek

With the change of pdf version the intelligent ocr also needs to be changed…please change both and see

Alternately try deleting the packages from this folder and redownload them again…looks like few references are not downloaded or are missing

C:\Users\<Username>\.nuget\packages

cheers

Deleting all packages and reinstalling them helped me fix the error. Thanks for the timely help Anil
