EADocX throws NullReferenceException – EA13 & EA14

[eadocX Support]

No – eaDocX looks in your Windows registry to find valid DLLs which it can use. And it’s possible they might not be there.
Are you able to download the full desktop version of Office ? eaDocX looks for some DLLs which are only present if you have a full download. The Microsoft Click-to-run option is good at fetching additional bits of Word which you might need whist you are using Word through the normal UI, but eaDocX uses an API DLL to get into Word.
