Do you have a sample of that PDF that you can share?

Any PDF I try to extract the data, it gives this message. To run this OCR need to have installed something?

Have you tried the Google OCR ?


What Windows and what version of Studio are you using?

Please check if you have MODI installed (Install MODI for use with Microsoft Office 2010), as it is required to use Microsoft OCR.

Following @balupad14’ s suggestion, do you have the same problem with Google OCR?


Only Microsoft OCR that is in trouble, google ocr works, but Microsoft works much better for reading images, I’ll try to install the mobi, I’m using Windows 10 64bit, Office 365.
