Attempt to download again; when you click on the download link, click save,
or save to disk, then when the save dialog window opens look at where it's
saving to by clicking on the drop-down box at the top of the window. You
may see your download there in the main part of the window - you can also
right click on it and view properties and copy the path to where the file
exists. Paste this path into the address bar of Windows Explorer and it
will take you there so you can install.
