This error message is often caused when the user does not have administrator privileges on the computer. To run most installations on Windows XP machines, you are often required to be the administrator of the computer or have some level of administrator privileges. The reason installations require administrator privileges is that installations often access the Windows registry and Windows system folders. If you are trying to install software on a computer in a corporate environment, you need to contact your system administrator to give you administrator privileges on your computer.
