Update error Developers version


I want to update some missing nodes (p.e. the chemistry part) in the Developper´s version (started from eclipse).

In the KNIME-workbench I go to "File"=>"Install KNIME Extentions". After selecting the Software I want to be installed and clicking the "Next"-button in the Install-Window the following error is occuring:

"Profile ID_Self_is not registered.


Is there anybody who can tell me how to install further available nodes in the Knime developer version?

Thanks so far!

Are you sure that you have write access to the Eclipse installation directory?


yes, I checked this out - there should be no problem with this...

but thanks anyway!
