Plugin is not work for Adobe Reader DC SDK

For the use of a non-development machine you must build a Release version of the plugin.

To develop plug-ins for Acrobat or Acrobat Reader you will need Acrobat. It is not free. The SDK is a marketing tool for Acrobat, if you want to see it that way.  To make plug-ins that load in Reader you need a special license and fee. The license is only given in certain cases - for example, you must not make a plug-in for Reader that would save people from buying Acrobat by allowing editing!! The fee is variable, up to $25,000 per year for DRM plug-ins.

Plug-in loading and initialization

When Acrobat or Acrobat Reader is started, it searches the plug_ins directory (co-located with the Acrobat executable) to locate and load plug-ins. In addition, Acrobat or Acrobat Reader searches folders that may be located within this folder. This search goes one level deep.

Acrobat and Acrobat Reader display a progress message in the bottom line of the splash screen at start-up. As each plug-in is loaded, the progress message shows the plug-in name. No plug-ins are loaded if the Shift key is held down while Acrobat or Acrobat Reader start. Also, if Acrobat or Acrobat Reader are running in certified mode, no third-party plug-ins are loaded.

I don't know how they work. don't know if it is related with my problem.

Thanks,

Tony
