Install the PC application (Mobiola Webcam v3.0.11 s60v3.exe), then copy the both files from the 'Cracked Files' directory into the install directory (C:\Program Files\Mobiola Web Camera for S60 by default).

Install the SIS file on your phone.  Start the PC application, choose your connection (USB, Bluetooth or WiFi), and then run the application on the phone, and choose the correct connection there as well.
