Uninstall Kettle 4.2 Community Edition

Hi,

I downloaded and setup Kettle 4.2 community edition but now I need to download the Enterprise Edition 4.2.1 (need to hook up to an enterprise server for contract work) and I think it would be best if I completely remove the community edition. How do I do that to make sure I have removed everything and get a clean install for the EE? I've been looking for hours but can't find anything on removing it. There is no uninstall file.

Thanks!!
Randy
