- disconnect from internet (until activation is finished)
- start the setup
- at installation choose "I have a serial number" and generate a key with the keygen
- at the setup click on "Options" and deselect "Product updates"
- after installation is finished activate the product via phone activation
  copy the hardware code to keygen and paste the unlockcode from keygen back to
  the app - voila!

NOTE: When install is running, keep keygen open and dont press generate a new serial,
      because the hardwarecode depends on the installation serial.
      Copy the hardwarecode without "-" to the keygen.
      For example, if your hardwarecode is: XXDW-IXV1-RN0I-3EUH-2U48 then copy
                                            XXDWIXV1RN0I3EUH2U48 to the keygen
