Your browser may warn you that the type of file you are attempting to download may harm your computer. This is just a standard security notice that appears when downloading files of this type. Click OK to approve the download.

If your download doesn’t start correctly when you click on the download link, try the following:

  1. Move your mouse so that it points to the download link.

  3. In the pop-up menu, select “Save Target As…”, “Save Link As…” or any similar menu choice.

Some corporate networks have “firewalls” that prevent you from downloading software. This usually affects all downloads regardless of the source. We suggest you retry the download from your home computer.
