Does anyone know where the default port comes from when installing a new instance on Windows Server 2012 R2?
It constantly picks up the wrong default which is already running on the server (probably swapped over after installation) and the install fails and rolls back.
I installed again and this time without rollback but still allocated the wrong port so at least was able to manually update the cpf and then start the instance.
Would like a simpler solution to the issue and assume they are traversing some windows registry entry that may need updating.
