Not sure whether it should be here or under other software. I have a pl.hindi(2) sub-folder under the program files folder. I do not why (and if) I installed it, Does not show up in the add/remove programme under control panel, and the SWI-Prolog site does not provide any indication how to uninstall it. Is it linked to some other programmes that I may be using? If not, how to uninstall it? Just remove the directory? Then any dll and registry entries would remain. Many thanks.
