I have tested the scenario and the files are non minimized. I have installed the latest internal beta release and the destination folder is: C:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q2 2012 BETA\Skins
. Checked both base and skin specific CSS files and they are non minimized. A short video file with my test could be seen at: http://screencast.com/t/QsV31UyLghI
Could you provide a similar test video to show us what should be the problem?
