You can use the latest version, but there have been some changes to the api. Like for example when running bitcoin cli you have to first create a wallet and use fallbackfee.
You should use the appropriate binary for your os and architecture. Most probably win64.
I’m having problems creating a wallet. Can anyone help? Using a PC.
if your Running in regtest mode use this command
bitcoin-cli -regtest createwallet “wallet_name”
if your using to do this Testnet then
bitcoin-cli -testnet createwallet “wallet_name”
how’d you get bitcoind running? i just downloaded the version ivan suggested (0.17.1), and it had not bitocind program when i “show package contents”… just 3 folders and some parameter files… i see the bitcoinqt executable, but no other executables…
for finding bitcoind, which is NOT included in the .dmg but requires the tar.gz download, your answer was almost perfect (and nevertheless extremely helpful: thank you!); just scroll down a bit looking for bitcoind instructions for mac (and all the associated terminal commands):

Thank you. Glad I found your post by searching. Since I am completely new to coding, didn’t know how to “load” the wallet.
Thanks for the advice. It finally worked! I got an error message, that it failed to create new database, and that database already exists. But I then repeated the command getnewaddress, and this time it worked, and I got a new address. I do not know why the error message was shown, when I entered bitcoin-cli --regtest createwallet “wallet_name”. Anyway, the address finally was made!
By the way, it looks like you put 2 hyphens before regtest, but there should only be 1 hyphen, -regtest
Worked for only with the following commands:
./bitcoin-cli createwallet “wallet_name”
./bitcoin-cli -rpcwallet=“wallet_name” getnewaddress

Previous versions of bitcoin client, didn’t had this feature. . . later this got added! to define a specific wallet name. . which does help for advance programming.!
