What probably happened is that you downloaded the program, but couldn't find it on your disk afterwards.

Try this:

• click on the Start button
• choose Find...
• choose Files or Folders...
• type "HLSetup" into the resulting window
• change "Look in:" to "My Computer"
• press Find Now

If the file (named HLSetup or HLSetup.exe) appears in the bottom of that window, you're all set: just click twice on it in that window, and it will automatically open and install Holiday Lights for you.

If the find doesn't show the file, then something went wrong with the download; visit our Download Center and scroll to the bottom of the page to have it e-mailed it to you instead so you don't have to worry about downloading it.
