The redistributable installer is an executable that contains the following:

keyman.exe	Main Keyman program
keyman32.dll	Keyman keyboard manager
kmshell.exe	Keyman configuration and user interface
keyman.chm	Keyman help file
klicence.htm	Keyman licence details
kmredist.inf	Redistributable installer information file
kmuninst.bin	Keyman uninstaller
lpng.dll	PNG image library

As well as these files, there will be one or more Keyman package (.kmp) files. The user can choose to install any 1 or more or none of these packages.

The executable is stored as a PKZIP-compatible self-extracting archive. You can open the archive in WinZip or other similar programs, but modifications through these applications may damage the self-extracting stub program.
