You can download the evaluation copies of UpFront from this page. To install the evaluation:-

1) Unzip the files to a temporary directory on your hard disk. You should now have three sub directories (disk1, disk2 & disk3) containing files.

2) Run setup.exe from the disk1 directory.

The evaluation will run for 30 days and has a limit on the amount of editing that may be carried out.
