The end-user license agreement (EULA) for Native Instruments products allows installation on two computers (three computers for all versions of MASCHINE and KOMPLETE). It is not allowed to use your installations simultaneously.
If you replace one of your computers it is not necessary to deactivate an existing installation, but due to the license agreement it is required to uninstall the product from the previously used computer.
If your computer crashed or you replaced the hard drive and it is not possible to uninstall the NI product, proceed with the activation on the new computer. You will still maintain the number of activations granted by the End User License Agreement.
Please do not create a new account! Always use the same login (email address) to activate on a new computer, as your serial number is connected to your Native Instruments account.
