[General](https://hub.acctivate.com/articles/troubleshoot?hsLang=en#general) April 14, 2025 # Resolving "Acctivate is already running." ## Close Acctivate or its login screen. If neither show on your computer, use Task Manager in Windows to close the program. If you receive the following message: ![AlreadyRunning](https://help.acctivate.com/wp-content/uploads/AlreadyRunning.jpg) This means that Acctivate  has already started and may be running in the background.  Most commonly users may have double click to open Acctivate while the logon screen is behind an existing window.  The log on window does not show in taskbar.  Click OK and minimize your windows until get to the desktop.   If you do not see the Acctivate logon screen you may also press Ctrl+Alt+Del and end task if you see Acctivate in your task list.  Then attempt to launch Acctivate again. You'll want to check both normal apps and Background process sections: ![2022-12-14\_12-46-13](https://hub.acctivate.com/hs-fs/hubfs/2022-12-14_12-46-13.jpg?width=442&height=464&name=2022-12-14_12-46-13.jpg) If you still are given an error, try rebooting your computer. -
