What if the Armory Wallet you are using has 3 separate PrivBase58 keys? How would you import this (move it) into Exodus Desktop? Exodus seems to want one key only when you select the move option from their latest (Windows 10) Desktop version 21.1.7.
Not sure it matters but the wallet has pre-2017 BTC.
I was trying to refer to this instruction: How to obtain the private key of an Armory wallet?
