Reinstall SEE Finance 2 for macOS if ever needed. The program is document based, similar to text editing and spreadsheet programs, which means the program stores your data in the document data file(s) that you setup and use in the program. On macOS, data files are always stored separately from the program itself. This allows you to delete and reinstall the program without deleting any of your data file(s) for the program. On iOS, data files can be stored within the app itself or elsewhere such as on iCloud Drive. You need to make sure your data files are saved elsewhere before you reinstall SEE Finance 2 for iOS.
