From Dictionary.com, uninstall is a word, but uninstallation is not. I tried deinstallation and that isn’t a word as well. Is there any word equivalent, ending in -tion that is a real word?
Answer
I think a good antonym for “installation” is “removal”. It doesn’t end in -tion, but it is a clear word which refers to taking something out. (On the other hand, installing is putting something in.)
Interestingly, uninstall is only used in a computer science context.
