Can LDD be installed on external Harddrives?

Hey Guys,i wonder if LDD can be installed on external Harddrives so it doesn`t need to be installed on a Computer.I ask because a Friend who works as a Security Guard would love to use it during Breaks at Work or between patroling through the Office Building he works in.The Computers in the Counter can be used freely for the Security Guards but of course you can`t install or download anything on these Computers for security Reasons.

Yes, it can be! But the program will leave a Lego creations or something simillar file in the user folder. Also I dont know how well the USB stick will handle the large amount of read/write cycles since it has to run the program.
