LICENSE & VERSION FAQ
Where can I purchase Delphi? How much does it cost?
You can view pricing and purchase Delphi from Embarcadero Sales, one of our valuable partners, or our online Embarcadero Shop site.
What is Update Subscription for Delphi?
The purchase of Update Subscription is mandatory at the time you purchase your Delphi product or upgrade. The Update Subscription agreement gives you a year of upgrades (including major and minor upgrades) and a specified number of support incidents. See the Update Subscription page for more detail.
Where can I get the latest updates for Delphi?
Updates and additional software for Delphi users are available on the registered users download page at http://cc.embarcadero.com/reg/delphi. Notifications for those upgrades are delivered via email and the upgrades can be downloaded via the Maintenance Portal web site by following the instructions in the email.
Who qualifies for the upgrade pricing on Delphi?
You can visit our online store and the upgrade qualifications page for more details.
Academic products do not qualify for upgrade pricing.
Which editions are available and what are the differences between the editions?
Delphi is available in five editions – Starter, Professional, Enterprise, Ultimate and Architect. See the Delphi product editions page and feature matrix for details on the differences between the editions.
Which types of licenses are available?
Delphi is available with multiple licensing options including:
- Individual named user licenses delivered via electronic software delivery (ESD) as a download and serial number. Discounted 5-packs and 10-packs are also available.
- Network Named and Concurrent user licenses managed using Embarcadero AppWave provide the additional flexibility of managing licenses on a license server plus software provisioning
- Network licenses managed by Flexera FlexNet are available on a special request basis
- Academic individual licenses for students and educators as well as volume licenses for classroom use
Are earlier version licenses included with Delphi?
Yes. With Delphi Professional edition and above, you also get access to licenses for earlier versions. See the Delphi Previous Versions web page for further details.
Can I give away or sell my older version licenses?
No. They are considered part of your license and are tied to your user account. They cannot be given away or sold.
If I already had an earlier version and requested my free earlier version license, why do you send my same earlier version serial number again instead of a second one?
Your earlier version license, and the version you upgrade to, are considered one named user license that covers both versions. If you already own an earlier version and go to the web page and request the same version license, you will just get a re-send of your existing serial number.
If I buy an Architect or Ultimate edition, why do I only get Enterprise editions of some of the older licenses?
Some of those earlier products are only available as Professional and Enterprise editions.
Why is there a limit of 180 days to request my earlier version licenses?
We can't guarantee that the older versions will be available indefinitely so you should be sure to download your earlier version software and licenses within 180 days.
Which localized languages are the older versions available in?
The earlier versions are available in English, French, German and Japanese. For versions 2007 and later, there is a single download and you choose the language at install time. For version 7, there is a separate download for each localized version.
What are the limitations of the Academic editions?
The Academic edition can be used only for learning in an academic or classroom environment. Educational institutions cannot use the academic version to produce software for use within their institution to commercial licenses.
What is the support status of different versions of Delphi?
See the Supported Versions List for the latest information by version.
Why do I have to request the older serial numbers and downloads separately? Why don't you just send them all at once when I buy?
It could be a little confusing for some customers when they purchase Delphi and receive seven different serial numbers and download links. We tried to keep it simple by just delivering the license for the purchased version and allow you to request the other licenses as needed.
Why can't I get version 2006 or the much older versions?
Version 2006 included some third party licensed code that we are no longer able to ship. Delphi 6 and earlier were discontinued years ago and we don't have plans to bring them back.
Why can't I manage Delphi 7 licenses via my network license manager?
Those versions used an earlier version of our licensing technology.
Do I have to register my copy of Delphi?
Yes. When you first run the product, a small application will open and ask you to register the product. Once that is done, and your product key is validated, then your product will be registered and installed.
How is InterBase licensed in Delphi?
InterBase XE7 Developer Edition is InterBase XE7 Server licensed for up to 20 users (80 database connections). The InterBase software is automatically installed with a default install of Delphi and licensed with your Delphi serial number. An InterBase ToGo developer license is also included in your Delphi license. You can deploy InterBase ToGo for testing purposes using the ToGo Test Deployment serial number included as part of your Delphi order delivery email. This is not available for AppWave Network license users.
When you're ready to deploy applications using InterBase, Embarcadero offers a variety of editions (Desktop, Server and To-Go) and a variety of licensing options (flexible server licensing, multi-packs and OEM licensing). Contact Embarcadero Sales or partners for more information. See the license terms in the Delphi license.rtf file for additional licensing details.
To obtain your free IBLite deployment license, use the IBLite serial number in your order delivery email and follow the instructions to generate a license file that you will use to distribute IBLite with your Windows, OS X, Android and iOS applications.
Where can I find the open source project for the Subversion integration in Delphi?
The open source project is http://sourceforge.net/projects/radstudioverins/. The repository for the open source code is available from the "Code" tab when you're logged in to SourceForge web site or at https://radstudioverins.svn.sourceforge.net/svnroot/radstudioverins/trunk/.

Supported deployment platforms
PCs and tablets with Intel/AMD processors running Windows 7, 8, 8.1, 10, Server 2008, or Server 2012. Macs running OS X 10.9 or 10.10. iPhone, iPad, or iPod Touch running iOS 7 through iOS 8.4. Android phones and tablets: ARMv7 devices with NEON support, running Ice Cream Sandwich (4.0.3, 4.0.4), Jelly Bean (4.1.x, 4.2.x, 4.3.x), KitKat (4.4.x) and Lollipop (5.x).
Will applications built with Delphi run on older versions of Windows including Windows Vista, XP, 2000, 95, 98 and Me?
Because of the use of Unicode as the default string type, Windows 98, 95, and ME will not run applications produced with Delphi 2009 or later. These operating systems do not support Unicode strings, and Microsoft has dropped support for them.
Applications built with Delphi 2009-XE2 and VCL will run on Windows 2000 or later. Applications built with Delphi XE3-XE5 will run on Windows XP and later. Applications built with Delphi XE6-XE7 will run on Windows 7 later.
Will apps created with Delphi run on all Android devices?
Apps created with Delphi are designed to run on Android phones and tablets: ARMv7 devices with NEON FPU support, running Android Gingerbread (2.3.3-2.7), Ice Cream Sandwich (4.0.3, 4.0.4) Jelly Bean (4.1.x, 4.2.x, 4.3.x), KitKat (4.4.x) or Lollipop(5.x). Compatibility may vary based on device hardware and specs. Click here for more details on the supported Android versions and devices, including devices we have tested.
Can I develop OS X and iOS apps if I don't have a Mac computer on site?
You can use an online service like MacinCloud to run OS X apps that you create with Delphi and you can use MacinCloud to test your iOS apps in the simulator. Access to a physical Mac machine is required for on-device testing.
Can I write a single application to deploy to both Windows and OS X using C++Builder and FireMonkey?
Yes. You can create a single application and deploy to Windows and OS X. You can also create iOS and Android mobile apps from the same codebase.
I'm wondering about moving my existing code to Unicode. What do I need to do?
Most existing code will work fine using the new default UnicodeString. Code that does byte level manipulation of string data, or that carries data in string variables probably needs to be examined and perhaps updated to account for the new character sizes inherent in Unicode string data. For more information, see the documentation and Embarcadero Developer Network for information about moving existing code to Unicode.
Can I open my projects created with earlier versions of Delphi?
Yes, you should be able to do so, depending on the installed components required by your projects. Delphi uses the MSBuild system for the build engine, and thus requires a new project file if you are upgrading from version 2007 or earlier. However, the IDE will seamlessly update your projects to the new format.
Can I develop .NET applications with Delphi?
No. Delphi produces native Windows and OS X. You can import .NET assemblies as COM objects, but the code produced by Delphi is strictly native code.
Why do I need to install the Microsoft .NET runtimes and SDK with Delphi?
Some of the functionality of the IDE requires these software packages.
Will my users / customers need the .NET runtimes / SDK in order to run my apps built with Delphi?
No. Applications produced with Delphi do not require any .NET runtime support. The product produces native compiled Windows applications based on the Windows API.
What are the differences between the ER/Studio Developer Edition data modeling capabilities in Delphi Architect and the standard ER/Studio product?
The ER/Studio Developer Edition data modeling and visualization in Delphi Architect is a subset of the full ER/Studio. Delphi Architect doesn't include metadata import/export capabilities or access to ER/Studio team repository servers. It includes limited reporting functionality (HTML only). The ER/Studio functionality in Delphi Architect supports a specific set of databases in line with those supported by dbExpress, while the full ER/Studio products offer flexible configurations for those databases and more.
Can I install Delphi on a machine with previous versions of RAD Studio, Delphi or C++Builder on it?
Yes, Delphi coexists nicely with earlier versions of RAD Studio, C++Builder and Delphi.
Are there new COMPILERVERSION and RTLVERSION values defined for Delphi?
Yes. For Delphi, COMPILERVERSION is set to 28.0, and RTLVERSION is set to 28.0.
Can I get certified as a Delphi developer?
Yes. See the Embarcadero Certification Center web page at certification for information on the Delphi developer certification program.
Is the Delphi 64-bit compiler available and how can I get it?
Yes, the 64-bit Windows compiler is included in Delphi.
What do I need to do to move my existing 32-bit Delphi applications to 64-bit?
The Delphi 64-bit information page has videos, information, resources and tips on creating 64-bit applications with Delphi.
