Errors in connection to the authentication
server
• Unable to connect to the authentication server.
→ Make sure that the computer is connected to the Internet.
The authentication server may be very busy now. Try to
connect to the server later.
• Access key cannot be issued because the PRODUCT ID is
wrong.
• Access key cannot be issued because registration code is
wrong.
→ Make sure that the PRODUCT ID or the registration code is
correct, then try to install the software again.
• New access key cannot be issued because this PRODUCT
ID has already issued access key.
→ The license for this PRODUCT ID has already been used on
a different console. If you wish to install the software in
another console, you must de-authorize the software license
on the current console. When you de-authorize the software
on the current console, you will be unable to use that
console until you re-install or re-authorize the software on
that console.
• Unable to de-authorize because unregistration code is
not in agreement with the information when access key
was issued.
• Cannot de-authorize as unregistration code is wrong.
→ Make sure that the unregistration code is correct, then try to
de-authorize the software again.
• De-authorization is not required as access key has not
been issued for this PRODUCT ID.
→ Check the PRODUCT ID that was used to install the
software, then try to de-authorize the software again.

• "Protocol Error"
• "Vendor Error"
→ This message appears when the installer is checking the Flash
Update version. This is not a malfunction.
• "Please grant authority"

authorization is complete, you can use the system software.
