Update out on July 1, 2020 (v.11.2.1 Build 3929) but can't find a changelog.
Still a big fan of this program, it's saved me a lot of time and trouble and does many things better and faster than Adobe Pro. Some more notes building on my above post ...
Resource usage
RAM: 25 megs
Download: 263 megs
Extracted: 373 megs, most of it comes from the included OCR Tools. Delete unnecessary languages to save space.
Processor: Doesn't appear to use any processor when idle, unlike Acrobat. Also unlike Acrobat, actually closes when you exit the program.
Steps
1. Download and extract with Uniextract2
2. Launch BytescoutPDFMultitool.exe
Status: still not portable, still writes to HKCU\Software\Bytescout. The program only has a handful of settings so this is probably adequately portable for most, but doesn't meet site standards:
License: Commercial use requires a license ($20 USD at this writing), also has an advert in the top-right corner but I didn't find it distracting / annoying.

Screencaps
NOTE: Selecting
RPA tools - Visual App Builder doesn't appear to do anything. It opens a web browser and whatever was at it's destination was offline.
