Installed the freeware-portable version on a thumb drive, inserted the SharewareOnSale exclusive license key and it appears anyway to be a fully-licensed version with no limitations.  Apr 14, 2017 review scared me enough to not install on my hard drive.  Seems like the best of both worlds.

jdownloader aint a must-have, but its best app of that kind. It supports so many great features that you elsewhere miss.
Installation is a bit strange, but when done and it runs you will start to love it as i do.

Thanks for the suggestion.  Installed and found it consumed 208 MB disk space which seems rather large. Am trying Free Download Manager 3.9.7.1638 Lite mainly because of its smaller footprint.

Sumo Pro 5.6.5 available here, today only from Giveaway of the day.  Codes also enable portable version.
