For example, Office Standard 2019, Office Professional Plus 2019, Office Standard 2019 for Mac can only use C2R installation technology, but they contain different suites. Only the different office versions will result in different office functions. For example, Office 2016 supports MSI and also supports C2R, but no matter which installation method youĬhoose, as long as you install the same version of Office 2016, you will get the same features. If an Office product allows C2R and MSI installation technology, then there is no impact on its features, because this is the same version of Office.
