Little Setup Builder is a tool for creating simplified install programs. Little Setup Builder assembles and packs an install program, an uninstall program if existing, the files to install, and the support files in a single executable file.

Since the install program produced by LSB consists of a single file, whose size must necessarily be manageable by the OS, it is not indicated to include applications whose overall size exceeds 20MB.

LSB makes use of Windows' basic installation functions; this allows incorporation of the file version identification system implemented through VS_FILE_INFO resources. This update features minor enhancements and bug fixes.
