I got This message"The project ‘C:\Users\as\Documents\UiPath\BlankProcess2\project.json’ could not be opened:Access to the path ‘C:\Users.nuget\packages\uipath\19.4.7054.14370\build\UiPath\aahook.dll’ is denied" when I click on Process to open a new project on UIPATH, I have tried to change the permission but it didn’t work. I have downloaded the latest 2019 edition
Can you try running the application with elevated rights?
If it means Run as Administrator then I’ve tried. I have also given full control rights but it’s not working. I am using version 2019.4.2 on Window 7 Home Basic.
Uninstall UiPath and when you reinstall, run with administrative privileges.
Try clearing nuget cache also.
Welcome to our UiPath Forum! 
My bet would be the antivirus software. Could you whitelist Studio and make sure the file is actually in this location?
Thanks all! I am actually using another machine now.
