Media Streaming Files You Must Include With Your Application

The installation procedure creates a directory tree for the LEADTOOLS files, and adds the demonstration programs and online help to your desktop. You specify the root directory during installation. The following subdirectories for the Multimedia Media Streaming features are created:

Subdirectory Description
Bin\CDLL\Win32
Bin\DotNet4\Win32
Redistributable Media Streaming feature files for Win32 systems
Bin\CDLL\x64
Bin\DotNet4\x64
Redistributable Media Streaming feature files for x64 systems

For more information on how to set a license, see Setting a Runtime License.

For step-by-step instructions on how to deploy the media server to another computer, refer to Deploying Your Media Server.

* For more information on the evaluation mechanism and the DSKernel object, refer to the Evaluation Mechanism Overview and the LMDSKernel2 Object.

*** It is best to install the x64 runtime in the %windir%\SYSWOW64 folder instead of the %windir%\System32 folder because some development environments (like VS8) will not import references that are placed in the %windir%\System32 folder since that is a 32-bit application.
