People have been having problems using these save files since the game
save file format was changed in the 2016-11-22 update. The save files in this package are in the old format.
I have a report that the following steps work to use this with the latest version of the game (new save file format). It will give you the 100% save game but it will NOT grant you all the achievements:
- Exit the game if it's running.
- Make sure you have at least one autosave file named "sr4save_autosave.sr4s_pc" in the save directory.
- Take Steam offline.
- Make a backup copy of your save directory.
- Delete the autosave file "sr4save_autosave.sr4s_pc".
- Copy only the file "sr3save_00.sr3s_pc" from the RAR package into the save directory.
- Start the game, select CONTINUE. That should restore the 100% autosave file from the RAR package.
Note: The SR4 save directory is "C:\Program Files (x86)\Steam\userdata\<user_id>\206420\remote".
