When I try to install new extensions, the little circle just keeps on going and the extension doesn't install.
When I go to extensions through the window>Extensions, it says there are three but only two work, onOne Software, which is installed on my machine, is empty.
When advised to download the Adobe Support Adviser, I follow the link to the page, only to be told that Adobe doesn't support this anymore.
Why can't I install any of the extension that I want and where are the onOne Software extensions?
