Whenever I try to install the latest build a message pops up saying I have a more current build installed. The build I have installed is 1.0.73. I uninstalled 1.0.73 and installed 1.0.8 but it was not working properly also. It was as if some of the features were missing. (I had installed 1.0.74 and found it not working properly and so resort to 1.0.73). I am using Windows 7. Is Windows 8 better for Rhino 5 and its plug-ins?
