Alternatively referred to as reload, reinstall is the process of installing a software program over the version that is already installed. This step is commonly performed when a program has worked in the past, but now is experiencing issues that cannot be resolved. To reinstall a program or operating system, install the program the same way you did in the past. If prompted about the program or directory already existing choose continue to overwrite.
If a reinstall does not work, it is suggested that you uninstall the program, and then install the program again. If you are ever concerned about losing your data, you should backup your personal data before uninstalling or reinstalling a program.
