Thanx for your help

Answer 1

Jason Lewis is right. Just comment out the openssl extension in your php.ini, run the command again in cmd shall fix your problem. No need to restart your PC or server.

Answer 2

You should not be calling update. You should first call install.
As for the create-project method, I also had the same problem. But it went away.
Please consult the documentation fully when attempting an install.
