I purchased a p12 certificate but am having difficulty using it. I always get the following error when trying to sign my app:
Error creating AIR file: Unable to build a valid certificate chain for the signer.

This is not an issue when I sign the app with a self-signed certificate.
I’m trying to sign a .air file for the desktop. I’m on Mac OSX. Is there anything I must do before using the p12 file?
I have previously (2 years back) purchased a p12 key from the same provider and that one did not have any issue. That key has expired now though.
After looking around I was able to generate a new P12 certificate which works. Yay!
