Press ctrl + shift + esc to launch the task manager. Click on the Processes tab and sort the processes according to the command line column. Now search in the command line column for the same folder that contains /tools, click on it and click on End Process button. This will force all processes that use the same folder to be closed. Now open the SDK Manager again as administrator and it will work.
