Troubleshooting:DLL Error when trying to install/uninstall Age of Empires III - The Warchiefs

DLL Error when trying to install/uninstall Age of Empires III - The Warchiefs

I uninstalled Age of Empires III and Age of Empires III - The Warchiefs in order to do a fresh install.
I was able to install AoE III without a problem, but when I try to install AoE III - TWC, Windows 7 seems to think the program is still installed and
attempts to uninstall it again.
When I let it try to uninstall, I get this error:

Error Number 0X80040702
Description: Failed to load DLL: FirewallInstallHelper
Setup will now terminate

So, I can't install the program because the "installation" tries to uninstall, but I can't uninstall due to the above error.

Hope someone can help.

Thanks, Ramesh, for your response.
After spending two frustrating days running registry cleaners; installing, uninstalling, and reinstalling multiple times with various degrees of failure; and ultimately two system restores, I was finally able to get the
game up and running.
I just hope that things are fully sorted out so that I don't experience these types of problems going forward.
