Writing Hyperlinks

I'm writing a company intranet site,and on the home page,I'd like there to be links to some of the software that the employees frequently use on their own computer.This will be the inducement to get them to use the intranet home page as their default home page, and visit it frequently.

For example a program which is under:

"C:Program FilesNow SoftwareNow Up-to-DateNUD.exe"

if I write that link into the hyperlink,it will not work,because the hyperlink also adds the url as a prefix to the link, so it will say

"http://www.url.com/C:Program FilesNow SoftwareNow
Up-to-DateNUD.exe"
