PERMISSIONS

An application cannot perform a task if the user running it doesn’t have the appropriate permissions. Although this is true of any operation a program must perform, permission issues are particularly common when working with files, and recent versions of the Windows operating system are particularly strict about enforcing permission requirements.

A common mistake is for developers to build and test an application while logged in as a user who has a lot of privileges. Sometimes, developers even have system administrator privileges, so their programs can do pretty much anything on the computer. To ensure that users will have the permissions needed by an application, develop or at least test the code using an account with the privileges that typical users will have.
