so you should just install core and follow the "pathing" guide in Armory's webpage: https://btcarmory.com/docs/pathing
Core's data dir should be launched from the directory specified in armory's config files.
Note: If you've downloaded from bitcoinarmory.com instead of btcarmory.com, you have the outdated version.
I'm trying to load Armory to see if I can recover some old fraction of btc from an old wallet
Do the above or just export the private keys and import it to Electrum 
(do this while offline - works without downloading the whole blockchain):
Click "Wallet Properties" then, "Backup This Wallet".
Check "Export Key Lists", then the button with the same name below, type your password and a window will open.
Check "Include Unused (Address Pool)", check "Omit spaces in key data" (below) and find your address from the list and copy its private key WIF (PrivBase58).
Download Electrum from the official site: electrum.org
Use, "Import Bitcoin addresses or private keys" when creating a new wallet, and paste your private key there.
