As one other and Jojo69 suggested I used bitcoin-abc-0.16.1-win64. And it worked just fine.
Maybe not with your operating system.
there is an ABC hard fork coming up May 15 so you might want to get everything done before then.
So their forking BCH also. Interesting.
I moved my BTC and BCH coins off of Armory. Their is only one developer left and we still don't have a BTG signer available. These coins are worth a significant amount of money. Sort of like a stock split or dividend.
Hardware wallets have software to separate the significant coins. You can have many different types coins on them without downloading the blockchain.
you shouldn't necessarily concerned. ABC has made it clear from the beginning that they are planning hard forks q6mo as routine upgrades. i don't necessarily agree with that but i believe their intentions to be good. we'll see. i agree that we should be able to harvest altcoins but i'm sure you'll get some sort of response like code it yourself. i've heard goatpig is a hard core fundamentalist when it comes to BTC so don't be surprised if you don't get your wish. good luck
