Hello, i want to transfer a few btc addresses from Armory Wallet to Electrum.
I have extracted the private keys from Armory : the ones are PrivBase58 and the others are PrivHexBE.
After installing the latest official version of Electrum Wallet, using the next chain :
Wallet-Private Keys-Sweep-Enter private keys /Electrum let only to enter these with PrivBase58/ i receive only this message:
"No inputs found.(Note that inputs need to be confirmed)"
What to do

My purpose is to load the balance of the addresses in Electrum and to handle them, because iam out of nerves to wait 5 or 6 days in order Armory to load the blockchain...
First of all you should have created your own thread instead of bumping this one year old one. The OP was trying to sweep keys to an offline wallet and that was his problem.
So obviously make sure electrum is connected to the net. There should be a green orb icon in the bottom right corner of the electrum window.
To add to what Hi-Tec99 said your private keys should be in wallet import format. They look like this:
>For private keys associated with uncompressed public keys, they are 51 characters and always start with the number 5. Private keys associated with compressed public keys are 52 characters and start with a capital L or K.
