In order to recap - the whole process I follow (
and where I stumble...) I am editing it as we go along. Please feel free to interject so that we can solve this issue once and for all.
Step 1) Updated the Apple Certificate on PC and MAC with the new one and rebooted (just in case!);
Step 2) Create a new project on B4i;
Step 3) Create a new "Sign Key" : insert First Name and Last Name, copy the same data into Organization, enter the country code and set the password. The files B4i.p12, B4i.keystore and certSigningRequest.csr are created in the KEYS folder;
Step 4) I log into Apple Developer Area and create the Developer Certificate. I upload the certSigningRequest.csr generated by B4i and I get this error
at this point if I had only a PC, I would be stuck at this point.
I try to solve the empasse turning on my MAC in order to create a CSR compliant with Apple.
ON MAC:
Step 5) Open "Keychain Access" and select the option
Certificate Assistant >>
Request a Certificate From a Certificate Authority
Step 6) Enter the (same) email in the User Email Field and the (same) name in Common Name. Select the option "Saved To Disk" : the CSR file named CertificateSigningRequest.certSigningRequest is generated and I saved in the B4i folder
