• There is no functional difference between the Store and Portable versions
• The Store version can be updated through the store and will not leave any data after Tiefsee is deleted
• The Portable version requires the installation of .NET Desktop Runtime 8 (x64) to run
• The Portable version can use 'portable mode' by creating a PortableMode folder next to Tiefsee.exe, and all data will be stored inside

If there are no special requirements, it is recommended to use the Store version

The Store version packages the entire .NET runtime environment into the program during compilation, and Microsoft has not yet proposed an effective solution
