CA always works diligently to deliver quality software to our customers. During a given instance of our testing, we found an issue with the recently released NFA 9.3.7, so it has been temporarily disabled for download until the issue is fixed. The issue has been given our highest priority and we want to assure you of our best efforts to resolve the issue in a timely fashion. Until CA informs you of our resolution of the issue, we request that you defer your plans to upgrade to NFA 9.3.7. We are sorry for any inconvenience this may have caused you.
If you have already upgraded and are having any issues please contact support and we will gladly work to assist you.
We will keep you updated here with all updates.
Update:
The tentative date for this release is Nov 2017. Appreciate your continued support and apologize for any inconvenience.
