Hello Stefan,
Generally when it comes to hosting on our servers - we ask customers to add dns entry for support.yourdomain to our server ip which takes some time to propagate and unless the subdomain is completely propagated we cannot proceed with installation as vision license is domain dependent.
Otherwise if you see installation steps of vision you would see it takes two minutes to install.
Rest your all tickets are resolved now - if you have more questions please email us or even you can have us added on Gtalk -
thevisionworld@gmail.com -- we provide support on IM too.
