Yes. With Delphi XE4, you also get access to licenses for earlier versions – Delphi XE3, Delphi XE2, Delphi XE, Delphi 2010, Delphi 2009, Delphi 2007, and Delphi 7. See the Delphi Previous Versions web page for further details.

No. They are considered part of your XE4 license and are tied to your user account. They cannot be given away or sold.

Your earlier version license, and the XE4 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.

Some of those earlier products are only available as Professional and Enterprise editions.

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.

Those versions used an earlier version of our licensing technology.

It could be a little confusing for some customers when they purchase Delphi XE4 and receive seven different serial numbers and download links. We tried to keep it simple by just delivering the XE4 license and allowing them to request the other licenses as needed.

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.

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.

RAD Studio XE4 is the multi-device and multi-language solution for developing across iOS, Windows, and Mac with a single codebase and script-free Intel/ARM native performance. Visual development and built-in enterprise class database support enable you to rapidly prototype and deliver your business applications on multiple devices and databases with a single development effort. RAD Studio uniquely supports both native and HTML5 UI options for flexible multi-channel solutions.

If you're interested in Delphi XE4, in combination with development tools for C++, Java, PHP, Ruby on Rails; plus a complete range of database design, management and performance tools, Embarcadero All-Access is the solution for you. Embarcadero All-Access XE provides all the application development and database tools you need – when you need them. It's the easiest to use 'toolbox' solution for any size team of developers, architects, performance testers, and DBAs. All-Access is ideal for both large enterprise teams working on a wide range of technologies; and for smaller teams, consultants, and individuals who find their time split across the software development life cycle.

Support and Maintenance can be purchased at the time you purchase your Delphi product or upgrade. The support and maintenance agreement gives you a year of upgrades (including major and minor upgrades) and a specified number of support incidents. See the Support dropdown menu item of our web site for additional information.

With Support and Maintenance, you get the latest feature updates and upgrades as they are released. The mobile functionality in Delphi may have frequent upgrades and feature updates. Support and Maintenance is generally the most cost effective way to stay up-to-date with the latest versions.

Updates and additional software for Delphi users are available on the registered users download page at . More major new feature upgrades are available only to users with current Maintenance agreements. 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.

Delphi is available in English, French, German and Japanese. The installer lets you choose any combination of languages and it's easy to switch between languages in the IDE.

Delphi is available with multiple licensing options including:

  • Individual named user licenses delivered via electronic software delivery (ESD) as a download an serial number. Discounted 5-packs and 10-packs are also available.

Yes. You develop applications on the Windows OS that is most productive for you, so you can develop applications on your choice of operating systems (Windows 8, Windows 7, Windows Vista, XP, Server 2012, Server 2008 or Server 2003). Applications built with Delphi will run on all of those Windows versions plus Windows 2000.

The DataSnap Mobile Connector feature generates connectivity code that you can incorporate into mobile applications for iOS, Android, Blackberry and Windows Phone 7. You develop your mobile applications using the standard development tools and languages for each platform such as Objective C with the Xcode IDE for iOS, Java for Android and Blackberry, or Silverlight for Windows Phone 7. You then use the DataSnap Mobile Connector code to provide connectivity to your native C++Builder or Delphi DataSnap server.

To install, you will need to have installed on your system:

  • The Microsoft .NET Framework 2.0 or higher
  • The Microsoft Visual J 2.0 Redistributable Package
  • Windows Internet Explorer® 6.0 or higher
  • MSXML 6

The installer will install the prerequisite software if you don't already have it installed.

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.

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.

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.

No. Delphi produces native Windows and Mac. You can import .NET assemblies as COM objects, but the code produced by Delphi is strictly native code.

Some of the functionality of the IDE requires these software packages.

No. Applications produced with Delphi do not require any .NET runtime support. The product produces pure native Windows applications.

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.

Yes, Delphi XE4 coexists nicely with earlier versions of RAD Studio, C++Builder and Delphi.

Yes. For Delphi XE4, COMPILERVERSION is set to 25.0, and RTLVERSION is set to 25.0.

Yes. See the Embarcadero Certification Center web page at certification for information on the Delphi developer certification program.
