I have downloaded Object Desktop Manager from this link https://cdn.stardock.us/downloads/public/software/objectdesktop/objectdesktop_setup.exe
And I have also downloaded Start11 30 days trial version from the official website.
In the Objet Desktop Manager I have checked the box where it says "Show beta downloads".
Then I go to Start11 and tell it to check for updates, but it says, "Your copy of Start11 is up to date." Version 1.11
It is not updated to version 1.15 Beta.
Thank you and sorry for so much inconvenience.
