What do the "No accounts detected" and "No installations detected" errors by Messenger Key mean?
MSN and Yahoo Messengers store account information in a registry. The fact that Messenger Key fails to find any installation or account on your system means that MSN/Yahoo Messenger installation or this registry record must have become corrupted. Unfortunately, Messenger Key is unable to recover a password in this case.
To recover your password, please try other methods described in our Knowledge Base.
