You don't currently have permission to access this folder

I'm trying to understand the error on Windows 7, "You don't currently have permission to access this folder."

The folder is c:windowssystem32tasks, but it could be any system folder.

I'm in an Admin account. I open Explorer and check effective permissions on c:windowssystem32tasks for the admin account, and everything is checked.

So why do I get the "You don't currently have permission to access this folder" error when trying to open the folder? And what permissions does the Continue button set that hasn't already been set?
