Failing To Install Solaris Studio 12.4 On Solaris OS 11.3 (Doc ID 2304441.1)

I am trying to install solaris studio 12.4 on solaris 11.3 updated to SRU-28. The document 2304441.1 says I should be using the https://pkg.oracle.com/solarisstudio/support repository. However when I try that I get:

>>>

pkg set-publisher -G '*' -g https://pkg.oracle.com/solarisstudio/support -k /export/home/metatst/pkg.oracle.com.key.pem -c /export/home/metatst/pkg.oracle.com.certificate.pem solarisstudio

pkg set-publisher: The origin URIs for 'solarisstudio' do not appear to point to a valid pkg repository.

Please verify the repository's location and the client's network configuration.

Additional details:

Unable to contact valid package repository: https://pkg.oracle.com/solarisstudio/support

Encountered the following error(s):

Transport errors encountered when trying to contact repository.

Reported the following errors:

https protocol error: code: 401 reason: Unauthorized

URL: 'https://pkg.oracle.com/solarisstudio/support'

Additional Details:

This account is not entitled to access this repository. Ensure that the correct

The license agreement required to access this repository has not been

accepted yet or the license agreement for the product has changed. Please go to

https://pkg-register.oracle.com and accept the license for the product you are

However I cannot see how to request access to the solaris studio support repository.

Regards,

John.
