Summary:
When clicking "Check for updates" in Version 9, an error "Application updater is not installed" is returned.
Cause:
The update installer is a separate application to Version 9 and is added to the machine during the installation of Version 9.
Some users who install Version 9 without Administration rights are prevented from accessing the update installer or users who have had the software installed by someone else who was not logged on as them.
Resolution: Ensure you have sufficient permissions to install the software under your login, then reinstall the software
