If you click the “OK” from the 「Program Authorization Complete」 dialog box, you will be prompted with the following message box. The message box informs that it is required to install the MP3 encoder for audio recording, conversion and extraction.
LAME is the most frequently used MP3 encoding engine. It is a free software and open source project without any restrictions for use.
If LAME is not installed on the system where liteCam HD is installed, please download LAME 3.98.4 version from the following link.

LAME 3.98.4 Final Version Downloading Page: link2
If you unzip the files after downloading LAME 3.98.4 final version, you will find the "lame_enc.dll" file. You are required to copy this file to the directory where liteCam HD is installed in order to complete installing LAME. In general, you will find the directory by following "C:\Program Files\RSUPPORT\liteCam HD" . If you have 64 bit Windows, installation folder will be located under "C:\Program Files(x86)".
You can download LAME through other links, but it is recommended that you install it after downloading LAME 3.98.4 final version from the link provided above. 3.98.4 is the latest as of Jan 20, 2011 and it is tested with liteCam HD. If you see later version, you can still install 3.98.4.
