Karsten Silz,
Thank you for the screenshot. Apparently, certain upgrades could still be missing, hence it shows up as upgrade to Apply MyEclipse 9.1 update. Please select the same under – Dashboard tab > Updates available by selecting the checkbox and click on [Apply x changes] and follow the wizard.
Alternately, you could re-install using pulse.
1. Open Pulse. (Refer https://www.genuitec.com/forums/topic/installation-where-are-the-myeclipse-files-and-folders/ on the location of pulse explorer or download the same from http://www.poweredbypulse.com)
2. Login to pulse, you could also login anonymously
3. Select “Eclipse – Helios” realm from top left hand corner dropdown
4. Select “MyEclipse for Soring 9.1” from “My Profiles”, right click on the same and click on [re-install and run]
5. This will open a wizard which will guide you through the rest of the steps.
Let me know how this works for you.
Best
