TIP: Signing-related Issues

Hi all!

Here are the common issues you may encounter when using the developer certificate.

[B]I am receiving an “Unable to install a protected application from an untrusted supplier” error message when installing my app signed with the developer certificate.[/B]

These are the possible reasons for receiving this message:
[LIST][*]You have signed your application with an expired developer certificate .crt and .key pair. Check the .crt information and request for a renewed developer certificate if it has expired.[*]You are using an older version of the .crt/.key pair with a newer certificate installer. You must sign your application with the same .crt and .key pair issued with the developer certificate installer.[*]The IMEI is not present in the developer certificate. [URL="http://support.publish.nokia.com/?page_id=105"]Contact us[/URL] to recreate the developer certificate with the IMEI added.[/LIST]
If you require a new developer certificate, please [URL="http://support.publish.nokia.com/?page_id=105"]contact us[/URL].

[B]I am receiving a “Failure. Cannot provision certificate database (-14)” message when installing the developer certificate on my phone.[/B]

This message indicates that there is already an older certificate version on your device leading to a conflict in your certificate database. To resolve this, do the following:
[LIST=1][*]Go to Settings -> Application manager -> Installed Apps -> Nokia R&D Certificate Provisioner and uninstall the file.[*]Reboot your device.[*]Install the renewed developer certificate .sis file[*]Check that the dates are valid by clicking the certificate details of your new certificate.[/LIST]

If you require a new developer certificate, please [URL="http://support.publish.nokia.com/?page_id=105"]contact us[/URL].

If you are unable to find a solution for your signing-related inquiry, please post in this forum.
