# SetEnvironmentVariable

> Create or update a project environment variable with the SetEnvironmentVariable command in ABBYY FlexiCapture FCAdminTools, setting its value and type.

You can use an environment variable to specify a general setting for a project. You can use the `SetEnvironmentVariable` command to create such an environment variable. If an environment variable with the name you specify already exists, the command will change its value and description; otherwise, a new environment variable will be created.

<Note>
  You cannot change the type of an existing environment variable. If you specify a different type for an existing environment variable, the command will return an error.
