Error message when you try to install a game: "Setup cannot install system files"

When you try to install any one of the products that are listed in the "Applies to" section, you receive the following error message:
Setup cannot install system files or update shared files if the files are in use. Before continuing, close any open applications.
This error message occurs when you install software on a computer that is running any Microsoft Windows operating system. If the files that must be updated during the installation are being used by other programs, the files are not updated until the computer is restarted.
We suggest that you close any nonessential programs such as Microsoft Office, Microsoft Works, Microsoft Internet Explorer, and Microsoft Windows Media Player before you install any new software. Additionally, we suggest that you restart the computer after any software is installed to make sure that the installation is completed successfully.
Sometimes, you may want to restart the computer by using a clean boot procedure before you install software.
