Hi, Brian
I just downloaded the LazyCam 3.00.2_Update, The LazyCam.exe in it is 3.00 and not the 3.00.2 ver., Don't no Why though.
The LazyCam_Update is the one you want, It has the updated dll's used in LazyTurn and should be the latest.
Sound's like that's the one you have installed, Most of the dll's file's have a Date of 03/31/2008.
Hears a copy of LazyCam 3.00.2.exe, Just re-name it to LazyCam and copy it to your C:\Mach3\ folder (Std. default location}.
I've never had any issues with installing new ver.'s on-top of previous ver.'s hear.
Hope this Helps, Chip
