What is an iup file and how do I open an iup file?
IUP files are the software update files used by the Fritz application developed by ChessBase. These data files contain important data used for the upgrading of software from one version to another. When there is an available new software update, they are usually downloaded automatically. IUP files contribute a lot to making an application more updated and upgraded in terms of functions. When there are instances that the Fritz software is not automatically updated, manually updating the software can be applied by users. They can do this by downloading the IUP file. After that, they need to place the file within the Fritz installation directory and finally run the IUPgrade.exe program. This is usually included with the software installation. ChessBase Fritz runs on a Windows operating system and it is known as an online chess playing program that offers everything that chess players would want in a chess game. Users can also choose beginner, club player or professional before playing the game using the software.
