Where to put save file ?

I have a game that can be installed by a .exe. The save file is created in the same folder than the other files of the game. The issue is that, if the game is installed in a protected folder like Program Files, the save file can not be created or used because of restricted access. I think to create the save file in the AppData folder, but I don’t know if it’s a good way to solve my problem as this folder has not the purpose to contain save files. Is there a way to overcome the restriction of the Program Files folder ? If not, where would be the best place to put save files ?

Thank you for your responses. I will use the AppData folder to put my save file.
