The Administrator installation works like the WebClient installations of previous releases. An Administrator installation creates a single installed copy of a WebClient application on a machine to which all end users on that machine have access. To accomplish this, the install writes the WebClient and WebClient application information to areas that are common to all users of that machine, such as the HKEY_LOCAL_MACHINE (HKLM) registry key and the C:\Program Files directory. Using these shared areas requires write permissions that, by default, are restricted to users with Administrator privileges. After installation, you also need these privileges to handle application updates and to download "As Needed" components.
For security reasons, many companies do not want to grant everyone Administrator privileges. To use a WebClient application in that case, administrators have to install the application and then grant limited write privileges to the application users. For more information on this, see the
Grantingwrite privileges .
An administrator controls this type of installation throughout its life cycle. The administrator must install the application, grant permissions to end users, and perhaps set up batch jobs to handle application updates.
