According to
https://www.genuitec.com/forums/topic/eclipse-home-is-undefined/
https://www.genuitec.com/forums/topic/eclipse_home-is-undefined-after-the-update/
I tried to reenter licensing info via Help -> CodeMix -> Update License -> Login, but the login process stalls (see attached screen shots)

I deinstalled and reinstalled the codemix plugin, but the error still exists.

Please help!

Thanks and kind regards, Christian

csee,

Sorry that you are seeing this issue.
Can you please clarify if there is a folder named extensions in the Eclipse installation directory?
If the folder is missing, then it could be a permissions issue when trying to create one.

In case the Eclipse is installed as root and if you are running as non-root user, then please run Eclipse as root and check if it works.
Alternatively, you can change the location of the extensions directory to the location which you have permissions for. Go to Window > Preferences > CodeMix > Miscellaneous > Storage page. For CodeMix Extensions, uncheck the ‘use default storage location’ and set the location to the folder where you have full permissions including write access, apply the changes and restart the IDE.

If none of the above suggestions help, then please reach us via Live Chat (Help > CodeMix > Live Chat) to help us quickly diagnose the problem.

Apologies for inconvenience caused. Please let us know how you get on with this issue.

Hi Swapna,
thanks for the very quick response! It was indeed an issue concerning root installed eclipse and running with non-root user. I gave access to the user and everything works fine now!
kind regards
Christian
