将许可归还给许可管理器,以便其他应用程序使用。
Once the extension license has been retrieved by the script, tools using that extension can be used. Once a script is finished with an extension's tools, the CheckInExtension function should be used to return the license to the License Manager so other applications can use it. All checked-out extension licenses and set product licenses are returned to the License Manager when a script completes.
