I can only start Calibre by clicking on the ikon on my startpage.

@Philipstelvio

1. click Start button
2. in search box type notepad
3. you should see Notepad.exe at top of results list - double click it
4. Easiest way to get the path to a library folder is to use Windows Explorer (that's the file manager not the internet browser). Windows-key+e will start Windows Explorer.
5. Browse to the location of the required library folder
6. Shift+right click the required library folder
7. Select Copy as Path. That will put its path into the clipboard
8. Go back to the Notepad window
9. Type calibre --with-library (nb: there's a space on the end)
10. Paste the clipboard (ctrl+v)
11. you should see something like this
    
    

    calibre --with-library "C:\Users\<your windows user id>\Documents\Main Library"

12. Save the file from notepad to your desktop with a file name something like CalibreMain.bat
13. Close Notepad
14. Double click the CalibreMain.bat icon (it will be a gear wheel icon)

Calibre should start with the required library
