You need install AviSynth v2.5.7 or higher, and .NET FrameWork v2.0 or higher.
The basic BeHappy is a folder (portable) with BeHappy.exe and AvisynthWrapper.dll.
You can create a DeskTop link with right mouse button over BeHappy.exe and Send to -> DeskTop

To add more features you can add a subfolder 'extensions'.

Add the subfolder 'encoder' (read the Readme.txt file)

Add the 'plugins' contents to ...\AviSynth 2.5\plugins folder is not required now (read the Readme.txt file)

WARNING: new plugin ffms2.dll require AviSynth v2.6 (always recommended)
