Looks like they found out and pulled down all translations Anyways, the download links above still work. EDIT: They pulled down the download links as well. EDIT: Links are working again, they released it officially today.
…actually, you need to also install .NET manually, it’s in \packages\dotNetFramework\dotNetFx-x86-x64-AllOS-ENU.exe on the dvd
I installed it on the Windows 10 TP in a VM and all works fine. I didn't check if the installer updated the .NET version, have to do this later. Anyways, since the links are down everybody who didn't had a chance to grab it will have to wait now. Maybe they make it publicly available as soon as Monday, there seems to be just a few days between compilation (file date stamps in the ISO) and release, according to information from CTP3. The weird thing is that they even make a CTP4 when a beta is already rumored to be released in November. I'm happy anyways, CTP4 finally brought back the option to have all-caps menu headers.
