Close the dialog box

Re-opening the Android SDK Manager.exe will quickly appear in the list of updates, select the package that needs to be updated, click the install packages to update.

Update do not use Eclipse, otherwise eclipse will lock the Android-sdk-windows folder and should run directly after locating the directory where the Android SDK Manager.exe is located.
