Error “Invalid User Credentials” when you install After Effects CS4 on Windows Vista 64

When you attempt to install Adobe After Effects CS4 on Windows Vista 64, the installation fails and displays the following dialog box:

“Invalid User Credentials. You do not have sufficient security credentials to install Adobe After Effects CS4.”

You are not prompted to authenticate with an administrator account, and using Run as Administrator gives the same results.
