Click on the executable file from Microsoft Office 2019 that was downloaded in the earlier phase to continue with Microsoft Office 2019 setup.

By default, the office will be installed in a 64-bit version (if you don't use a very ancient laptop). However, if Microsoft Office detects a previously installed 32-bit version, it will install this (32-bit) version. Also, if you've earlier installed a 32-bit version and prefer this time going for a 64-bit version, you'll need to uninstall the earlier version entirely. But first you need to verify whether your 64-bit software supports your processor and operating system or not.

By downloading them from the official website office.com/setup, you can also install language packs for Microsoft Office 2019. They can be downloaded free of charge, but according to the Office version (32-bit or 64-bit) you plan to install.

Be sure to closely read the setup directions and acknowledge the software license contract and terms and conditions.
Depending on the velocity of the processor and the RAM on your machine, the installation method will begin and take a few minutes.

Upon completion of the installation, make sure the product is registered and necessary accounts are created.
