Why I get the dialog 'CreatePocess failed'?

Question:Some time when I run a Rhinoresurf command, I see a 'Error' dialog which said 'CreateProcess failed'. Then, I can do nothing with RhinoResurf. Why?

Answer: This is because a file named 'resurfadd.exe' has been removed. When Rhinoresurf run the command, it will check the file 'resurfadd.exe', if this file has been removed, the program will stop and do nothing. The file 'resurfadd.exe' is stored in the folder of RhinoResurf plug-in ( (typically " C:\Program Files\Rhinoceros 4.0\Plug-ins\RhinoResurf\" for Rhino 4 (32-bit) and " C:\Program Files\Rhinoceros 5.0 WIP(64-bit)\Plug-ins\RhinoResurf\" for Rhino 5(64-bit) ) .

To fix the peoblem, download the file 'resurfadd.exe' from here http://www.resurf3d.com/rhinoresurf04/resurfadd.exe and put it in the RhinoResurf plug-in installation folder.
