Just tried to update from 2.9.0.0 to 3.0.0.0 through Subscription-Manager.
Checkbox for Delphi XE9 appears in installer, but does not install in Delphi XE9/10.
Also the subscription-manager still shows to update from 2.9.0.0 to 3.0.0.0 when Installation is finished.
Please check...
Thanks/Regards, Tom
Could you send the installer log file by direct email so we can investigate what exactly happened on your machine during install?
