I purchased the Free 4.6 upgrade (Thanks, Daz!) and it said that I should use the install manager to install it.
But it doesn’t show up in the install manager.
I’ve installed and updated other products with the install manager, so I think I’m familiar with how it’s supposed to work.
On the website, if I click on “My Account” it shows the order for the 4.6 upgrade as complete; I installed the latest Install manager (18.104.22.168)
