Has anyone come across using the "Upgrade an Existing Domain or Post Office to GroupWise 2014", only to have no Domain or Post Office listed, and 'add' does nothing?

I have a test systems with a simple GroupWise 2012 sp2 install, both are Windows 2008R2, no firewalls running....

One server is the Primary domain, the other a secondary domain and single post office, both have eDirectory 8.8 installed.
I installed GroupWise 2014 sp2 on both.

I ran the "Upgrade an Existing Domain or Post Office to GroupWise 2014" on the Primary domain, it showed on the list, went through the wizard and it was a successful upgrade.
I used the admin console, it showed the Primary domain as database version 1400, the secondary domain and Post Office as (2012).

When I try to use the GroupWise Install web page on the secondary server, I use the "Upgrade an Existing Domain or Post Office to GroupWise 2014", the secondary domain or post office don't show on the list.
Using the Add button, and browsing for the folder of the domain, does nothing to add it.

Thanks in advance.
