Where to best store app data on Windows

    For a standalone app I need to store some external data, so it's not overwritten when the app is updated or replaced with a new version.
    On OSX this is straightforward. I just write stuff to ~/Library/Application Support/Myapp. I am pretty safe to assume that I have permissions to create that directory and write things in it.
    On Windows I'm not sure about this. I haven't used the platform for ages but afaik there is "Program Files" but also possibly "Program Files x86_64" or something. And it is typically located on C:/ but it could be any other drive.
    What would be a sensible approach? Are there any helper functions in Max or the SDK that can be used figure out a location on any Windows system that won't get me into trouble?

      I found some standard W32 api. Makes sense to use that straight from my code. I wasn't thinking clearly :)
      TCHAR pf[MAX_PATH]; SHGetSpecialFolderPath( 0, pf, CSIDL_PROGRAM_FILES, FALSE );

      IMHO, on a multi-user machine CSIDL_APPDATA would probably be better.

      Thanks for the advice Emmanuel. I'll try that.
