Error Code #4

My licence hasn't been able to activate, and I just see Error Code #4. What can I do to fix this?

There are a couple of scenarios that can cause Error Code #4.

  • Your licence has been activated on the maximum (2) number of allowed computers.

For example, if you already have 2 computers, both with Serato DJ Pro licences activated, these will be using up the maximum activations. You will need to deactivate a computer before you are able to activate another computer.

You may have also been using a friends computer, or had licences active on a computer that you've now sold.

Once you've deactivated one computer, and logged in with the correct account on your current computer, the Serato DJ Pro licences should now be activate.

  • You've changed the hardware of your computer.

If you've activated a Serato DJ Pro licence or trial on your computer, and then swapped out the hard drive, or updated your BIOS for example, this changes the Host ID of your computer. This means that the your computer will continue to use one activation, but Serato DJ Pro won't be able to be activated for use.

Once you've deactivated the old activation, and logged in with the correct account on your current computer setup, the Serato DJ Pro licences should now activate.
