Installation Instructions for Empty Desiderata Valley. This only affects *brand new* Desiderata Valley, not any already being played. 
To generate new unplayed Maxis 'hoods, backup, then delete the 'Sims 2' folder in C:\Documents\EA Games.
Note: This works with all versions of the game. You may need to restore backups before installing any EPs or Patches.

Open C:\Program Files\EA GAMES\The Sims 2 FreeTime\TSData\Res\UserData\Neighborhoods 
Make a backup of the F001 folder by either zipping it into a zip folder or renaming to F001.bak.
Open the F001 folder. Delete everything inside the Characters folder and delete the file F001_Neighborhood.package 
Unzip the downloaded file, which is F001_Neighborhood.package. Place this into the F001 folder.
To uninstall delete the modified F001 folder and restore your backup.
