KAHLID,
You will find info on how to install LazyTurn in section 4.0 / page 5 of 31 of the Lazyturn manual.
Note, that in the manual, the latest posted version was Reply #637 and that is no longer true
as mentioned by Brett.
There is probably 20 different versions of the application file.
Lazyturn can be run independantly in a seperate directory ( which I would recommend).
Follow the manual instructions and let me know if have a problem.
