Do I have to register my license?

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. Note it is possible to register your product without internet access. On the registration dialog you will have the option to choose alternative means of registration.

What is the difference between Starter, Professional, Enterprise and Architect editions?

There’s a short answer and a long answer to this question.

The high level differences are that Professional editions of Delphi, C++Builder and RAD Studio do not include FireDAC support for remote databases (ie. databases running on a separate machine).

Starter is basically the same as Professional, but there is a licensing restriction on the amount of revenue you can generate before needing to upgrade.

Enterprise gives you full FireDAC database access.

Architect takes Enterprise and adds in additional Database productivity tools.

For more details on the differences between the editions, you should have a look at Embarcadero’s Product Editions page for Delphi, C++Builder or RAD Studio, or alternatively download the very detailed Feature Matrix available here.

How can I do mobile development in Delphi or C++Builder?

Mobile development features for Android and iOS are available in all version of Delphi, C++Builder and RAD Studio, with the exception of the Starter Edition.

When developing for iOS, you will also need a Mac computer for development and running in the simulator. You will need an Apple Developer account to test and deploy to iOS devices. Additional details are available in the online and product documentation.

Where can I get the latest updates?

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.

What is Update Subscription?

The first year of Update Subscription is included in the price of your purchase of Delphi, C++Builder, RAD Studio and other related products (like the Mobile and FireDAC add-on packs, etc). The Update Subscription agreement gives you a year of upgrades (including major and minor upgrades) and a specified number of support incidents.
