The Fate_Unretire program is a standalone executable file that will run from anywhere on your harddrive. I would recommend placing it somewhere near the Fate game folder so you can find it again.

When you perform step #1 below, you must find the folder where your saved games are located. From the Fate FAQ:
XP: C:\Documents and Settings\All Users\Application Data\WildTangent\fate\Persistent\SAVE
Vista: C:\ProgramData\WildTangent\fate\Persistent\SAVE

Don't forget that you have to reveal all hidden folders first if you go through the program.

Hope this helps with those persistent questions!

Instructions:
1. Open a savegame (file has .FFD extension).
2. Character's name and Descendant value will be displayed. Modify the Descendant value.
3. Possible values: -1 = retired, 0 = not a descendant, any other number signifies his place in the family line of descendants.
4. Creating a backup copy of savegame is recommended. Copy will have .BCK extension.
5. Click "Do It!" button.
Enjoy
