If you are unable to uninstall the game from the Control Panel using Add/Remove programs or Uninstall feature, a partial or failed installation of some files is preventing normal installation behavior.
Use the Uninstall Tool in the game folder or the Nancy Drew folder. If given the option to Modify, Repair or Remove, choose Remove.
If the Uninstall Tool is not available for this game, go to Start > Search and search by game title. Delete all results.
After uninstalling the game, search again by game title to verify all game folders have been removed from your computer. Any remaining game folders will be in one of the following locations (depending on the game title and your operating system):
C:Program FilesNancy Drew
For XP: ‘My Documents’ folder (C:Documents and SettingsUsernameMy Documents)
For Vista/7: ‘Documents’ folder (C:UsersUsernameDocuments)
NB: The folder in Documents contains the saved games for that game title. Deleting this folder will delete your saved games.
Empty your Recycle Bin.
Deleting these game folders removes the game from your computer. If a listing for the game still appears in your Add/Remove Programs list , the file size will now be 0 kb, and you can consider the game completely removed.
