To install a certificate for Adobe AIR, the certificate must be picked up using Mozilla Firefox on the same computer and user account that was used to enroll the certificate. Other browsers will not work.
When the certificate is issued, an approval e-mail will be received by the technical contact with a retrieval URL (e.g., https://products.websecurity.symantec.com/orders/enrollment/CertPickup.do?pin=56aaa).
Open the retrieval URL in Firefox, enter the PIN and click Continue. The certificate will automatically be installed; upon a successful installation, the following prompt will appear:
Your personal certificate has been installed. You should keep a backup copy of this certificate.
If the wrong computer or user account has been used when installing the certificate, the following message will appear:
This personal certificate can't be installed because you do not own the corresponding private key which was created when the certificate was requested.
For information on signing Adobe AIR applications, refer to article SO10161.
