File Share Encryption

I am trying to set up a new user with PGP10.0. I installed the software and added the appropriate license. I even went through the key setup wizard, but whenever the user tries to decrypt a downloaded file, it generates a message ( 3 unknown key(s) - It is not possible to decrypt this message because you keyring does not contain usable private key(s) corresponding to any of the above public key(s). What does this mean?

This usually means that the file is not encrypted to the user's public key - he/she can only decrypt files encrypted to his/her public key, because that is the only public key for which he/she has the matching private key.  If the key was generated off the user's machine and imported to his/her keyring, it might not have included the private key (in the export from the other machine - the private key is not included in an export unless specifically set to do so); if it did include the private key, it needs to be set as having Implicit Trust (right click on the key, select Properties).

Were you able to resolve this?
