When attempting to install Oracle VirtualBox, users may encounter an error message indicating that the Microsoft Visual C++ 2019 Redistributable Package needs to be installed first. This error arises because Oracle VirtualBox relies on components developed with Microsoft Visual C++ for Windows, which require the redistributable package to provide the necessary runtime components1. To resolve this issue, users must download and install the Microsoft Visual C++ 2019 Redistributable Package. This package is not included in the default Windows installation and must be obtained separately. Once the redistributable package is installed, users should be able to proceed with the installation of Oracle VirtualBox without encountering the error1. It's important to note that administrative privileges are required to install the redistributable package. After installation, a system restart is recommended to ensure all components are properly initialized for Oracle VirtualBox to function correctly.
