Mr_Noodle, I'm in the same boat with jbc424...
I tried searching the noodlesoft knowledge base and found nothing regarding Adobe Acrobat DC. Do you have a link? In fact, this thread is the only thing I could find specifically regarding getting Hazel to interact with Acrobat DC via scripts. From what I've read from various places online, none of the AppleScripts from past versions of Acrobat can be applied to Acrobat DC.
Like jbc424, I purchased PDFPenPro recently because it was apparently friendly with Hazel and the cost of ownership is less than Acrobat. However, I'm not a fan of PDFPenPro's OCR capabilities. I can't figure out how to achieve 300x300 dpi or better quality, accurate OCR, and file size less than 250-500 KB per page. I really want to figure out how to OCR in the most optimized way possible (before I go too far down the rabbit hole with a paperless filing system), and it seems to me that Adobe's "Editable Text and Image" (previously known as "ClearScan") is the only offering of its kind out there.
So, unless someone can correct my thinking above, I'd really like to figure out if it's possible to have Hazel execute commands within Adobe Acrobat DC, so I can decide whether to buy an Acrobat DC subscription. I thought about asking Adobe support, but I'd rather not buy a subscription just so I can ask the question.
