If you are a computer beginner, please read Installing SuperMemo for Beginners. It offers step-by-step instructions for downloading, copying files, and upgrading from earlier versions of SuperMemo, or updating SuperMemo to the latest release build.


In 5 seconds (brute force)

To uninstall, delete the folder in which you installed SuperMemo.

Remember that this will likely delete everything related to SuperMemo: collections, plan schedules, sleep timeline, etc. Deleting the folder manually may still leave 2-3 entries in Windows registry (if you let SuperMemo run in administrator mode).

In 30 seconds (smart)

You can uninstall SuperMemo (without removing your learning material) if you follow these steps:

  1. Run Control Panel
  2. In the Control Panel window, choose Uninstall program (in older Windows Uninstall or change a program)
  3. In the Uninstall or change a program window, scroll down to SuperMemo, and choose Uninstall

If you cannot find SuperMemo entry in Control Panel, use sm19unin.exe located in the SuperMemo folder (C:\SuperMemo by default).

SuperMemo Uninstall program was designed to remove only the files that have been added at installation. It should not delete your collections, plan schedules, sleep timeline, etc. If you want them removed, you will need to do it manually in your favorite file manager.
