Installation:

There is nothing easier.

1.Create a directory to place program in.
2.Unpack archive to that directory.(Note: run-time library vrobj.dll is requred
  to operate. Make sure you have one in "\OS2\DLL" or in directory with the 
  "E-Rotor") 
3.Start the program of installation INSTALL.CMD.
  
  Also the program e-rotor2.exe will be placed in your Startup folder.
  There is one thing that is not done automatically: INSTALL.CMD does not update
  your config.sys. You are to add your directory where "E-Rotor" is installed to
  LIBPATH statement of CONFIG.SYS.
