I found an old file called "Bitcoin_wallet_7-4-2017.dat" in a backup that I have. I downloaded the entire ledger with bitcoin core and copied the DAT file into the "wallets" directory. When I try to open it it just loads their forever, not doing anything.

Questions:

1.) How do I get the address out of this wallet dat file?

2.) When you backup a wallet, you just need the dat file right? Nothing else? Maybe it isn't a complete backup

3.) Any other way to get into what this wallet has?


Note I tried this: https://cryptomining-blog.com/9488-how-to-easily-recover-old-wallet-dat-private-keys-with-pywallet/

But it didn't work. Error:

WARNING:root:pycrypto or libssl not found, decryption may be slow

    Traceback (most recent call last):

    File "c:\zip\pywallet.py", line 2111, in parse_wallet

    d.update(parse_BlockLocator(vds))

    TypeError: 'NoneType' object is not iterable

Tried electrum too, that gave me a long hex error.
