Graboid video installer 4.71 social advice

Users interested in Graboid video installer 4.71 generally download:

Graboid Video is intended to download video from a huge collection of around a million clips, one third of them in high definition. Fortunately...

— I recently upgrade to Mac OS 10.15 - Catalina and realized afterwards that Graboid will no longer run on my computer because the Mac version is not 64-bit. Is there any solution to this?...
The only way around it is to downgrade back to the old OS per support. I did and that it was back to normal working but eventually I upgraded again and unfortunately am no longer able to use graboid :-(
