Thanks for your answer.

I am using the manual instructions.

I'm not looking for someone to diagnose the problem, I just want to know if anyone as managed to install the SDK successfuly in the past few days, just to know if I am doing something wrong or if it's just a temporary issue.

Thanks for the infos about the VM I hope it will come soon, I can't wait to start and I feel fairly motivated right now, but I tend to have a short attention span due to work and the 2 websites I run
