For users with 64-bit windows, and the program does not launch, a solution is, go to the installation folder of the program and make a copy of: c:\Users\<user>\AppData\Local\Programs\LucasChessR\bin\OS\win32\Engines\komodo\komodo-14.1-64bit-bmi2.exe.uci_options and rename it as: komodo-14.1-64bit.exe.uci_options
