i want use the Dependent Package (UiPath.UIAutomation.Activities) in 20.10.6，But the lowest version I can choose is 21.6.1
@blancetnoir Open “project.json” file in notepad and update the version number and save the file.
Close the project and open “main,xaml” project will load with your respective version
Welcome to UiPath community…!
Can you please confirm why you are looking for that specific version? Any issues with the latest version?
