Hello @szawadski,
can you share that simple workflow you created? Just in case .xml is not enough.
Before reinstalling KNIME I would do two things:
- export existing preferences (from within KNIME go
File --> Export Preferences...) and then importing them (File --> Import Preferences...) to avoid manual work (and not to forget anything of course!) - get list of all installed extensions as you’ll have to install them again (here you can’t avoid manual work but at least you’ll have list of extensions and then it will be easier to install them all). See here how to do that.
Br,
Ivan
