Can't find the AI 6 installer

I have a Yamaha THR10 which had a licence for AI6. I’ve installed it the past and have just activated a licence in the Download Assistant. But I don’t see AI6 as an option within the Assistant. In the support download area there is an updater for AI6, but not an install file for the software.
Can anyone point me to the installation file?
Many thanks

Hi and welcome,

Brilliant - many thanks!
