Can't install apps in Addon Manager

[salomon_grundy]

Hi:

How can I enable or install apps using the Addon Manager? If I want for instance ffmpeg pull down the State list and is says Not Installed. Then I try to tick the Enabled box but it doesn't check, It is the same with all the apps. What am I doing wrong?

You first need to select on which drive to download it - You can select sda1, click save, and after the page reloads you can click the enable checkbox (but I think it will be enabled by default).
