Can't install AOE 3 Expansion

im trying to install AOE but i keep getting a pop-up saying:

Age of Empires III was not installed for all users or the current user.
Please log in with the correct account. This set-up will exit.

I am the computer administrator, i don't know what else to do?

From the FAQ below

"Q. I encounter "Age of Empires III was not installed for allusers or
the current user. Please log in with the correct account. This setup
will exit." error, when installing WarChief's. What can I do?
1. Right-Click the Start button and select "Explore"
2. Navigate to the "All Users" directory, then "Start Menu", then
"Programs"
3. Create a directory called "Microsoft Games"
4. In that directory, create another directory called "Age of Empires
III"
5. Re-Run the War Chiefs install program. "

Hey i tried what you wrote. the same pop up still happens
it says something about the installshield wizard

I had the same problem, but followed what Katy Pluta wrote and that fixed it
and I was able to install the War Chiefs Expansion Pack.

Having the same problem. Tried uninstalling, re-installing. Cleared the registry manually. Warchiefs demo installed no problem, but the actual game, bought new from a shop, says AOE 3 not installed. Please help, it's driving me mad!

WHOOP it worked for me! thanks katy pluta. on vista i didn't even need to navigate to all users, because when i clicked "explore" on start button, the only file that shored up was the prgrams file. and when i clicked on it like 5 folders popped up. I pushed "organize in the upper left hand corner, added another folder (named Age of Empires III), and it worked
