This is because the associated driver itself still exists in the driver store and could be reused. Just uninstalling the add-ons, such as 3DVision, will not remove the corresponding package from the Installer2 folder. Method 1: Always uninstall the driver and other add-ons before installing a new driver. How can I reduce the size of the Installer2 folder? This is so the software can be installed if required during a rollback or other OS-initiated driver install. I did not install any driver add-on software, yet I still see the software files in the Installer2 folder.ĭuring a Custom Install, even though you might choose to not install a particular software add-on, the associated software files are still stored in the Installer2 folder. If add-on software was already installed and running, then there would likely be a version mismatch between the newly installed driver and the add-on software. Without this cache, only the driver would be installed. This allows device or OS-initiated driver installs (such as a driver rollback) to successfully install the corresponding add-on software that would otherwise be unavailable if the original install media was not present. The original installation media - whether a downloaded self-extracting executable, a CD, or network drive - does not need to be present as long as the files are stored in the Installer2 folder. The Installer places all driver and related add-on software in the Installer2 folder to ensure that re-installs and uninstalls are successful and complete. The native Program Files location is used regardless of the package type that is, Program Files (instead of Program File x86) is used even if the Installer and the software installed are 32-bit.Įach time a new package is installed, the Installer adds the package contents to the Installer2 folder. The cache location created is the :\Program Files\NVIDIA Corporation\Installer2 folder. When you install the NVIDIA display drivers (including other driver add-on software, such as 3DVision, NView, etc.), the NVIDIA Installer first creates a cache location on the local drive, copies the contents to that location, then performs the installation using those files.
