If you are using Unity 3.x, the upgrade price on the Unity 4 Pro base license and any Unity 4 Pro add-ons, is $750. So, a base license upgrade costs $750 and an upgrade per Pro add-on to Unity 4 costs $750. A basic Unity 4 add-on costs $125.

No, you do not have to upgrade, you can continue to use the products you have purchased and upgrade when you want to. We’ll keep delivering critical fixes for 3.5 at least through 2012. Right now, Unity 3.5.6 is out. Read this blog post on Unity 3.x and Unity 4 going forward.

Yes, you can activate a free 30 day trial of Unity 4 Pro even if you have already had a free trial of Unity Pro 3.x.

A Unity 4 license installed on a computer allows you to have any earlier version of Unity installed on the same computer with as many features that were available at that time. Please contact support for more information.

Please make a back up of your projects. Once you open your project in Unity 4, it will no longer open in previous versions of Unity. Unity 4 Pro is only backwards compatible for Web content created with Unity 3.x Pro. So, if you have published a browser-based game designed to work in Unity Web Player 3.x, your game will still work for users running Unity Web Player 4.x. However, this is the only exception.

Please consult the Upgrade guide section of the release notes before converting your project to Unity 4.

The Linux player is an excellent example of a grassroots movement in Unity. Over two years ago, developers started using their Fridays and free time to port the engine to Linux. The port made slow progress, but was kept alive and maintained over the years. At the 2012 Ninja Camp development week, these developers spent the week furthering the porting effort, and at the end of the week, they were able to show some compelling demos. Combine this with the recent success of commercial games on Linux -- for example the Humble Indie Bundle and games sold through the Ubuntu Software Center -- and it was clear we needed to give our customers a chance to enter into this still-largely-untapped market that is hungry for games.

Supporting a new platform is no easy task -- especially one that has a wide range of variations in hardware and software. It will take more testing and feedback before we will feel confident the quality is up to such a standard that we can ship a final version. However, this should not stop you from using it. Many games will run without Linux-specific problems on most modern Linux systems, and problems you encounter can be reported to us so we can fix them, resulting in a win-win situation for everyone.

"Yes! In order to export to Linux, simply pick the "PC, Mac, & Linux Standalone" platform from the "Build Settings" menu, select a Linux player as your "Target Player" and click build."

No, it will be free just like our PC and Mac Standalone publishing options.

Because Linux (as an operating system) runs inside of all sorts of devices, but this export option is specifically for 32 and 64-bit end-user desktop systems.

While games exported from Unity will run on most modern Linux desktops, we will (at this time) only be offering official support for Ubuntu 10.10 or later, with a graphics card that provides hardware acceleration.

With our new Licensing System, we allow you, the user, to manage your Unity license independently. Contacting the Support Team when you need to switch machine is a thing of the past! The system allows instant, automated migration of your machine, with a single click. Please read our guidelines, Managing your Unity 4 licenses available on our activation page.

No, this is not in the scope for Unity 4.

No, it’s assigned to the installation of Unity, you don’t sign over ownership.

Every paid commercial Unity license allows a *single* person to use Unity on *two* machines that they have exclusive use of. Be it a Mac and a PC or your Home and Work machines. Educational licenses sold via Unity or any one of our resellers are only good for a single activation. The same goes for Trial licenses, unless otherwise stated.

The free version of Unity may not be licensed by a commercial entity with annual gross revenues (based on fiscal year) in excess of US$100,000, or by an educational, non-profit or government entity with an annual budget of over US$100,000.

If you are a Legal Entity, you may not combine files developed with the free version of Unity with any files developed by you (or by any third party) through the use of Unity Pro. Please see our EULA for further information regarding license usage.

You’ll need to “Return” your license. This enables you to return the license on the machine you no longer require, which in turn enables you to reactivate on a new machine. Please refer to the guidelines Managing your Unity 4 licenses on our activation page.

Please ensure that your details are being entered correctly. Passwords ARE case sensitive, so ensure you’re typing exactly as you registered. You can reset your password using the link here. If you’re still having issues logging in, please contact support@unity3d.com

No, you can’t. In order to use Unity 4.x, you’ll need to upgrade to a 4.x license. You can do this online, via our Online Store.

As with changing machine, you’ll need to “Return” your license before making any hardware or OS changes to your machine. If you fail to “Return” the license, our server will see a request from another machine and inform you that you’ve reached your activation limit for the license. Please refer to the guidelines Managing your Unity 4 licenses on our activation page.

Please email support@unity3d.com explaining your situation, including the details below:
The Serial number you were using on the machine.
The (local network) name of the machine that died

The Support Team will then be able to “Return” your license manually.

You cannot activate both licenses. A single license may only be used on one machine at any one time.

OS X: /Library/Application Support/Unity/Unity_v4.x.ulf
Windows Vista & 7: C:\ProgramData\Unity\Unity_v4.x.ulf
Windows XP: C:\Documents and Settings\All Users\Application Data\Unity\Unity_v4.x.ulf

For any further assistance, please contact support@unity3d.com.

One Unity license is good for two simultaneous installations per seat. This is a courtesy service so that you may run Unity on both your laptop and desktop computer, for example. It may only be used by a single person, however, and not simultaneous usage by multiple people.

We license Unity source code on a per-case and per-title basis via special arrangements made by our business development team. As this can be quite expensive, we do not generally license source code to smaller operations, educational institutions, nor to companies in countries which do not have adequate legal intellectual property protection.

No.

We can assist in migrating your licenses from one computer to another if a system is replaced, repaired or lost. This is a process performed by our support department and takes about a day. Contact support@unity3d.com.

Console publishing is not included with Unity Pro - you will need a special Unity license for each platform on a per-title basis. First, you will need to be a registered developer with the console manufacturer or license holder, such as Microsoft, Sony or Nintendo. After you are registered and approved by the console manufacturer, you will need their devkit hardware and software tools. At that point you can purchase a console license from Unity Technologies for use on a per-title basis. Please use our contact form for more information.

We offer a special extension of the Unity webplayer which can cache asset bundles locally. This is licensed under an agreement made by our business development team. Generally it is licensed to developers with a large anticipated revenue and not on a smaller scale basis.

Sorry, such license mixing in the same company is forbidden. You may not, for example, use 9 free Unity licenses for development and a single Unity Pro license to publish the final game. You will need a Pro license for each team member.

Large entities with over $100,000 in revenue may not use any Basic Add-Ons in Unity 4. For more information, please read the EULA.

We have a reseller program for businesses which qualify. Feel free to use our contact form with more information about your business to apply.

No sorry, Unity licenses may not be sold and are otherwise are non-transferable.

Unity is delivered online as an electronic download. There is no disc, box, manual nor other physical product. Consequently there are no shipping fees with your purchase.

Please go to our license comparison page to read about what features are included in the free and Pro versions of Unity.

Subscriptions to student licenses are available through Studica. We also have educational licenses available to accredited educational institutions. Schools can contact us using our contact form for more information. Note that reduced-price versions available through Studica have a single activation and not the two activations that you get when you purchase a full-price Unity from the unity3d.com web store.

No, Unity does not charge on a per title basis and you do not pay royalties or pay revenue share, even for games and applications made with the free version.

No, Unity does not charge an annual fee or maintenance fee.

Sorry, we do not give away Unity Pro licenses for free nor offer a delayed payment plan. But we do care about developers of all shape and size, that's why we made a free, basic version of Unity available to the public. Projects you make with the free version are fully compatible with Unity Pro if you ever wish to upgrade later.

Yes, all assets in our tutorial and example projects may be used in both commercial and non-commercial use in Unity-based projects. The assets themselves may not be resold, however. Note that these assets are widely known in the games industry, so if you do use them in your titles it may be obvious that you re-used Unity assets.

Yes you can create and sell a game with the free version of Unity, without paying royalties or any revenue share. However, the free version of Unity may not be licensed by a commercial entity with annual gross revenues (based on fiscal year) in excess of US$100,000, or by an educational, non-profit or government entity with an annual budget of over US$100,000.

Please also be aware that the feature set of the free version is not intended for the production of professional games and interactive content. Lastly, games made with our Pro trial licenses may not be distributed nor used for commercial purposes.
