I am going nuts here,
I have a certificate from Thawte in my firefox browser.
according to the docs, I should be able to just backup the certificate in firefox and use it as the signing certificate in my air app (flash CS5). However it is not working, each time I try to publish I get the error "unable to build a valid certificate chain for the signer"
I have contacted Thawte and despite their every effort, I still cannot make it work.
Can anyone help me with this issue?
The certificate file needs to have the whole certificate chain.
When you export the cert from firefox, make sure to check the option to include the whole certificate chain.
