Create your own shortcut:
1. Go to Start > All Programs > HP > 1522
2. Right click the Scan application
3. Choose Send to > Desktop (create shortcut)
If the shortcut does not work then your scanning software is not actually installed. If that is the case then uninstall and reinstall with the latest software version from http://support.hp.com. HP will have a full solution available for both versions of Win7 so make sure you pick the correct 32 or 64 bit version.
