Once one I’m not able to create a fresh setup.

I tried Eclipse version 2022-03/2022-12/2023-03/2023-06/Latest Release/Lastet with Java 17. but all setups failed:

Took 47 seconds.
There are failed tasks.
Press Back to choose different settings or Cancel to abort.

Is there a way to update an existing setup (it seems that there is a new Karat version). I tried Maven->Update Project + Resolve Dependencies, but resolve fails.

@wborn any magic hint?

Did you solve this? I am getting the same error when trying to reinstall under windows.

EDIT: I may have fixed it by changing the install location from the default c:\program files\ to a different location that does not need admin rights to write to like c:\eclipse\ which is where I installed it previously probably for this reason and forgot.
