I am unable to install dradis 2.9 on windows 8 64 bit, please help me

I am new to this software and i am facing problem installing it on my windows.
The program is not able to download Ruby itself and unable to find it when mannually installed and as i am new to ruby i am unaware of gem files and how to install it, please help me and take me through the steps in installations on windows.

You don’t give us many details about what went wrong…

Ruby and Windows is not the easiest thing to get working if you are not familiar with it, maybe you should give Dradis a try using a Kali Linux VM?

Also, maybe this thread helps:
