When I signed the armory offline wallet, there was no response after entering the password.
The password is correct, because if I enter the wrong password, there will be a prompt, but I enter the correct password without a password error prompt.
What version of Armory are you using on the online PC?
What version of Armory are you using on the offline PC?
What version of Bitcoin Core are you using?
Can you post the logs from the offline PC?
Do you have your seed (12-24 words)? With the seed, you can just import your funds to a better wallet, such as Electrum.org
I understand you're just trying to help, but giving out incorrect information is not really helpful.
Armory does NOT use a typical BIP39 12/24 word seed mnemonic recovery mechanism. Armory relies on the concept of a "Paper Backup" that contains a "Root Key", which is a series of random looking 4 character groups like this:
The Armory root key is unique to Armory and cannot be used in any other wallet.
