64-bit setup script for ShapeAppMacroRecordingCSHarp sample

With 64-bit Windows, vsta registry entries must be changed from

32-bit registry: HKLM\\SOFTWARE\\

TO

64-bit registry: HKLM\\SOFTWARE\\Wow6432Node\\ 

I've attached SetupShapeAppMacroRecordingCSharp64.js to demonstrate these changes.

Since setup scripts write to the registry, remember to run the setup scripts as administrator in Windows Vista and Windows 7.  "run as administrator" can be accomplished by running CMD (commandline window) as adminstrator or by right-clicking on an executable and selecting run as administrator.
