The demo program you have just downloaded is Lace level 2, which is the "Proof of concept" of our technology.
When the disk scan finishes, a window will open and show you the Lace level of your disk.
Please make sure to press the "Analyze results" button at least after checking your first disk, for it will explain the meaning of the Lace Level factor.
This demo program measures only the first 80GB of each disk/partition, and will give you (if your disk is larger) a quick estimate of the situation on your disk.
Please continue now with the installation.
