Well, I ran into the same problem, when I tried to install the trial version of Keyboard Launchpad: "An administrator has blocked you from running this app".
Following the advices in above given links would mean to circumvent all security measures and install this software despite this stark warning! I am hesitant to do this, because Stardock "outsourced" this download to a third party site, out of their control (download.cnet.com). How can I be sure, there is no malware/virus/whatsover in that download?
