It worked for me, Make sure you extract it with something like 7zip in C:\Users\(your username)\AppData\Local\FalloutShelter and for me i had to make it auto rename after extracting it then rename the 2 files to Vault2.sav and Vault2.sav.bkp if you already have a Vault1.sav and Vault1.sav.bkp in the folder if not dont worry it wont even pop up.
