florianfj,
I could replicate it at my end. Thank you for reporting it. I have raised a PR for the team to fix it.
Alternatively you can use Pulse to install the ME 9.0. Here are the steps :
1. Open pulse(If you don’t have pulse, download the same from http://www.poweredbypulse.com)
2. Login to pulse
3. Select “Eclipse – Helios” realm from top left hand corner dropdown
4. Click and expand – Ready to use profiles > Popular
5. From the right hand pane, right click on “MyEclipse 9” and click on [run]
6. This will open a wizard which will guide you through the rest of the steps.
Let me know how this works for you.
