Windows: software won't stay open or not showing books.
This process clears the software cache in Windows. Your checkouts or holds will not be lost, they are saved on Cloud Library's servers under your library card number.

Windows 10, 7, or Vista:
1. Go to the Start Menu.
2. In the Search programs and files box, enter exactly %appdata% and hit enter on your keyboard.
3. This should pull up a list of folders. Delete the Bibliotheca folder. If there is also a 3M Cloud Library folder delete it too.
4. Once this is done, close the window you have open, and try reopening Cloud Library. You should have to log in.

Windows 8:
1. Go to the desktop area.
2. Hold down the Windows key on your keyboard (looks like a flag, usually near Alt) and press R.
3. This opens the "Run" box, enter exactly %appdata% and hit enter on your keyboard.
4. This should pull up a list of folders. Delete the Bibliotheca folder. If there is also a 3M Cloud Library folder delete it too.
5. Once this is done, close the window you have open, and reopen Cloud Library. You should have to log in.
