Hopefully you're not still waiting for the installation to progress.
First thought is to cancel the installation, restart the computer, and try the installation again. If the problem persists, verify that Windows Update is working properly, delete all temp files using CCleaner or another tool, then reboot again.
Note: When running CCleaner, you'll need to disable the setting to exclude recent temp files, then re-enable it after rebooting.
Let us know how it goes.
