I am currently running PAD version 2.36.140.23262 with Windows 10. Since upgrading to this version, my flows that use OCR are now failing.
To test this, I created a simple, one action flow:
Running the flow produces two different error messages, depending on file type.
For .JPG I get:
Correlation Id: 80a01f50-e3b6-4070-9277-a609b2892d38

Is this an issue with the current version of PAD or has OCR changed?
