Problem updating VSR 23.02 to 23.03

Using a Windows 11 Pro desktop PC (fully up to date) with VSR 23.02

I performed an update check and was informed that there was a new version available (23.03)

The update downloaded and the installer attempted to install it but hung at about 70%

The "Cancel" option did not work at all despite waiting for several minutes.

All I could do was to stop the task in the Task Manager.

I tried running the updater again but this time I got the message:

"This Veritas System Recovery product version is up-to-date. No updates are currently available"

The update definitely didn't complete as the installed version number is still shown as 23.02

What can I do now?
