“Windows cannot install required files” error when installing a third party storage driver during Windows setup
Consider the following scenario:
- You start Windows setup by booting using DVD media.
- The DVD drive is attached to a storage controller which is supported natively by the drivers supplied with Windows. However, you wish to install third-party drivers for this controller.
- During Windows Setup, on the page titled “Where do you want to install Windows?”, you choose “Load Driver” to install the third party storage driver. You install a new driver for the storage controller which your DVD drive is attached to.
In this scenario, you may encounter the following error message after starting Windows Setup:
Windows cannot install required files. Make sure all files required for installation are available, and restart the installation.
