Hmm, I have donloaded the installer on my Ubuntu 5.15.0-40-generic x86_64 yesterday, but nothing happens after execution. No window, no process, nothing. I contacted support and they proposed a reboot, which I did. Today, the linux installer is even not visible in the portal :( Any hints how to resolve this?

Oh, nevermind. If you use it locally or use X11 forwarding (it runs fairly well over SSH even remotely), the downloader retrieves the standard install script and everything is the same as before.

This is actually much nicer, since the downloader is a much smaller file to copy over the network and eliminates a transfer step. Nice!
