After looking at the download file, it appears that it is a .cab type file.
This is like a zip file.
I also noticed the following instructions on the download page where the
"Download Now" button was:
To download the template manually:
Click Download Now below.
In the File Download dialog box, click Save.
Select the folder where you want to save the compressed file (.CAB), and
then click Save.
Open the folder where you saved the compressed file, and then double-click
the file.
Use one of the following methods to extract the template from the compressed
file:
If the file opens in WinZip® or another decompression program, use the
program to extract the template from the compressed file. After extracting
the file, you can double-click the template to open it in the program it was
designed for.
If the compressed file opens in a regular window, double-click the template
file, select the folder where you want to save the template, and then click
Extract. Now locate the folder in which you saved the uncompressed template,
and then double-click the template to open it.
Follow the instruction above from the "In the File Download dialog box,
click Save." line and you should be able to work with file and save it as you
want to .
