Download:
Firstly go to the Slysoft site.
Click on Downloads You should see a screen like the attached.

As shown click on the AnyDVD & AnyDVDHD DOWNLOAD button.
This window should then appear.

Click on the Save button.
Saving files to your HD (Hard Drive) first is recommended.
Select where you want to save the file to.

On the completion of the download you can either click on the Close button (then install at later date)
or
Click on the Run button to install from the HD.
This is recommended. As it only takes a short time. So get it done & out of the way.
