Neo4j Desktop - upgrade not being loaded

I am using Neo4j Desktop and the current version on my machine is 1.2.4. I have seen the notification that version 1.2.9 is available, so I have installed it using the link provided. After the installation process is complete, Version 1.2.9 is running. The installation requested my administrator credentials during the process.

However, if I close Desktop down and then re-open, Version 1.2.4 comes up. What has happened to version 1.2.9?

Anticipating a follow-up question, I originally installed as a local/user application, not a system application (single user use).
