 after that It fails at the following at 2/43,

Fatal error occurred while executing install script (Certificate-generator package)

Is installs platform,tools, but stops at certificate-generator package).

I also tested the md5checksum of the downloaded image, it matched,

I’m using Windows 8 Development machine with JDK/JRE installed and path given,

is there a way to install fully and why does it fail at that package?
