Consider the following scenario. You upgrade a computer from Windows XP to Windows Vista. Then, you try to install an update for one of the following applications:
Windows Vista has new layers of security that help secure a computer from malicious software and from attacks. One layer of security is User Account Control (UAC). When UAC is enabled, the operating system does not automatically use administrator rights and permissions for applications that you run. The operating system does not automatically do this even when you log on by using an account that is a member of an administrative group. Updates for the .NET Framework and for Visual Studio require administrator rights and permissions. You cannot install updates for the .NET Framework and for Visual Studio unless you have administrator rights and permissions.
To work around this issue, right-click the application, and then click Run as Administrator.
When you click Run as Administrator, the rights and the permissions for the account are elevated to administrator rights and permissions. You may be prompted to enter the administrative credentials (user name and password) if you did not log on as an administrator. Or, you may be prompted to enter the administrative credentials if you logged on by using an account that is not a member of the Administrators group for the computer.
This issue does not occur when you install an update for the Microsoft .NET Framework 2.0 or for Microsoft Visual Studio 2005.
