For a number of reasons, upgrades of the free Reader can fail. Because Reader is a free download, I usually don't even bother to try to fix the problem, I just uninstall the version currently installed, and then download and install the latest version.

If this still fails, follow the instructions in the link that Almir provided. If this still does not work, there is one more thing you can try: Adobe's Cleaner tool allows you to remove any trace of Acrobat or Reader from your system, so uninstall Reader, run the Cleaner from and try to install again.
