No NI software on the target PC is needed to run the setup.exe generated for a CVI distribution kit.
To create a CD (or network directory) to distribute your software, just include all files CVI generates for the distribution kit. For example, CVI 6.0 creates a directory under your project directory titled cvidistkit.MyProject (if your project name is MyProject). Include all files in that cvidistkit.MyProject directory.
