I installed the 7.x-2.x-dev version of nodehierarchy in my D7 website. The website is multi-language and there are known issues between this module and some language related modules. I need to remove nodehierarchy for the time being as a result.

The module is not available on the "Uninstall" tab at admin/modules/uninstall. What is the correct way to uninstall nodehierarchy from my D7 website?
