Installing the PDFlib Block Plugin

To install the PDFlib plugin follow the steps below depending on your operating system.

The Block plugin and its sibling, the PDF form field conversion plugin, work with Acrobat 5, Acrobat 6/7 Standard and Acrobat 6/7 Professional on Windows and Mac, and Acrobat 8 Standard and Professional on Windows. The plugins don’t work with Acrobat Elements or any version of Acrobat Reader/Adobe Reader.

The plugins contain multiple language versions of the user interface, and will automatically use the same interface language as the Acrobat application if possible. If the plugin does not support the native Acrobat language the English user interface will be used instead.

To install the PDFlib Block plugin and the PDF form field conversion plugin in Acrobat 5, 6, 7, or 8 the plugin files must be copied to a subdirectory of the Acrobat plugin folder. This is done automatically by the plugin installer, but can also be done manually. The plugin files are called Block.api and AcroFormConversion.api. A typical location of the plugin folder looks as follows:C:\Program Files\Adobe\Acrobat 7.0\Acrobat\plug_ins\PDFlib Block Plugin

•	With Acrobat 6/7 the plugin folder will not be visible in the Finder. Instead of dragging the plugin files to the plugin folder use the following steps (make sure that Acrobat is not running):

•	Extract the plugin files to a folder by double-clicking the disk image.

•	Locate the Acrobat application icon in the Finder. It is usually located in a folder which has a name similar to the following:

•	Single-click on the Acrobat application icon and select File, Get Info.

•	In the window that pops up click the triangle next to Plug-ins.

•

Click Add... and select the PDFlib Block Plugin folder (for Acrobat 7) or the PDFlib Block Plugin Acro 5-6 folder (for Acrobat 6) from the folder which has been created in the first step. Note that after installation this folder will not immediately show up in the list of plugins, but only when you open the info window next time.

To install the plugins for Acrobat 5, start by double-clicking the disk image. Drag the folder PDFlib Block Plugin Acro 5-6 to the Acrobat 5 plugin folder. A typical plugin folder name is as follows:

Trouble-shooting. If the PDFlib Block plugin doesn’t seem to work check the following:

•	Make sure that in Edit, Preferences, [General...], Startup (Acrobat 6/7) or Options (Acrobat5) the box Use only certified plug-ins is unchecked. The plugins will not be loaded if Acrobat is running in Certified Mode.

•

Some PDF forms created with Adobe Designer may prevent the Block plugin as well as other Acrobat plugins from working properly since they interfere with PDF’s internal security model. For this reason we suggest to avoid Designer’s static PDF forms, and only use dynamic PDF forms as input for the Block plugin.
