I have compiled a list of Frequently Asked Questions regarding Licensing and Activation, that should enable you to bypass the most common errors our users are faced with, when trying to activate or migrate.
How many machines can I install my copy of Unity on?
Each Unity license allows a single person to use Unity on two machines that they have exclusive use of.
I receive the following error message upon activation: Your License has been activated too many times, please contact Unity Support.
The warning happens because you have already activated your copy of Unity on the allowed machines.
I want to move my Unity license to a new/alternative machine.
The migration procedure for Unity is pretty simple. Youll need to Uninstall Unity from the machine you wish to migrate. Thats your side done! Youll then need to send a Migration Request to the Support Team (email@example.com). The email will need to include the following:
- The Serial number you are using
- The name of the machine you are migrating from
- The name of the machine you are migrating to
- The name of the individual the Serial has been assigned to
The Support Team will then allow for migration, to your new machine.
Will uninstalling Unity from an old machine automatically allow for activation on my new machine?
No, The Unity Support Team will have to allow for migration of your license, meaning you can then proceed to activate on your new machine.
Can I use Unity3 with a 2.x Serial?
No, in order to use Unity 3, youd need to upgrade to a 3.x license. You can do this Online, via our Website store. https://store.unity3d.com/shop/
My license wont activate using the online activation procedure!
This may be due to one of many things. The easiest way around this, is to activate using the Manual Activation procedure. You can find out how by following the link below: http://answers.unity3d.com/questions/205/manual-offline-activation-of-unity
I have replaced an item of Hardware, now my copy of Unity needs to be re-registered.
Unity creates a licensing file that takes information from a number of places within your machine, making the file unique. When an item of Hardware is replaced, our Licensing servers will see this as a request from a new machine. As with the migration procedure, you'll need to email the Support Team (firstname.lastname@example.org) in order for them to reactivate your license.
The Editor freezes when waiting for a response from the Activation Server.
In some cases the Online Activation process seems to 'Hang' and takes a little longer than expected, when waiting for a response from the Activation Server. We advise that you wait it out for 5-10 minutes before exiting the Editor. Give the Manual activation process (Stated above) a try if the Online activation continues to hang!
Please read the FAQ before contacting email@example.com, as most Licensing cases are pretty trivial. Please let me know if you feel something that hasn't been covered here, ought to be.
