I have a customer which is using Reader 7.0 Version 7.0.9 english.
We have added the root certificate to his reader and configured that its valid for "Signatures and as trusted root" and "certified documents" in the certificate details I can see that the selected path is valid.
Our problem is, that in our signed invoice the signature is still shown an unknown. I have built up the configuration in our office and here it works. Do you have any idea what can be the problem?
