I’ve just updated my Expert Manager for RAD Studio with a few bug fixes and a little additional functionality. You can now see installation with no Experts node and you can enabled and disable experts via a check box.
There is a current a known issue where the tool does not display any installations on a Window 10 machine with a non-English set-up. If anyone else has experience this I would like to know.
You can get the executable and source code from the page: Multi-IDE Expert Manager
