您必须保持当前SDK版本的授权与更新，以便继续获取Viewer SDK不断的更新升级。因为目前Viewer SDK处在发展阶段，每月都会增加一些特性和功能，如：假如您现在使用PDF-Tools 版本3（版本4已发布），现在您需要升级到版本4，才可获得Viewer SDK的授权。

现有3款完全不同且可用在开发者应用程序中的PDF浏览产品-以下两者中可分开购买- 或者购买包含以下两者，类似于捆绑选择的PRO SDK。

Simple DLL SDK（已发布）所提供的函数集使开发者可以在其应用程序中嵌入窗口，实现PDF文件的浏览/打印。无论是图形用户界面的设计还是要采用所提供的哪个功能方法都由开发者决定，并且在开发者的产品中无可见的Tracker。

该ActiveX SDK（已发布）是一个功能齐全，并可与供终端用户所使用的PDF-XChange Viewer模版相合并，还可在应用程序中嵌入窗口。开发者可以隐藏并使SDK中的大部分控制器和功能不可用，并且能修改GUI。但是存在软件品牌跟踪，并需要从嵌入浏览器的’About’窗口中获取。ActiveX比Simple DLL拥有更多的功能特性。

Your existing SDK version license must be maintained as current and up to date to continue to access progressive upgrades to the Viewer SDK, as its very much in its development stages at the moment with new features and functionality being added each month - e.g. If you currently have PDF-Tools V3 (V4 has just been released) you will need to upgrade to V4 now to receive a Viewer SDK License.

There are 3 distinct products available for the inclusion of PDF Viewing within the developer's Software application - either of the below maybe purchased individually - or a PRO SDK containing both items below as a 'bundled' option.

The Simple DLL SDK (available now) provides the developer with set of functions to create a means to View/Print PDF files within a window embedded in their software application. Both the GUI design and means of employing the provided functionality is very much left in the developer's hands and no Tracker branding is visible within the Developer's product.

The ActiveX SDK (available NOW) option is a fully featured, ready to incorporate facsimile of the End User PDF-XChange Viewer, again embedded within a Window of the application, the developer is able to hide and disable most of the controls and functions within the SDK and some GUI tailoring is possible - but Tracker Software branding is present and required from the 'About' Window of the embedded viewer. The ActiveX is also more feature rich than the Simple DLL method.
