Q: I’m getting an “OCR Library is not loaded” error when trying to perform OCR on my document. How can I fix this.
A: This error is caused by a missing package on your Windows machine needed by the Tesseract OCR engine in PDF Studio.
The Tesseract OCR engine needs a Microsoft Visual C++ Redistributable package installed in order to work. Since nearly every Windows installation has a copy of this installed, PDF Studio does not come packaged with the Microsoft Visual C++ Redistributable in order to avoid having a larger installer file and installing a duplicate version of this package on our users system.
How to Fix This Error
In the rare event that you see this error message, you can simply install the Microsoft Visual C++ Redistributable package (latest version) from the Microsoft website. Once installed, the OCR function will work without any further issues in PDF Studio.
