This makes me curious, do other language clients work on Windows at all? It seems highly unlikely that we're the first to encounter this error as there have been many language clients for much longer.

php-ide-serenata has only just switched and Windows users now immediately encounter this error.

It also seems fairly strange that tests pass on appveyor

Hmm, I think I see what the problem is (#166), it is because Serenata is using an unstable version of the atom-languageclient - intentionally, I might add, since I need the targeted commit to fix an issue with autocompletion.

It is likely it'll be solved by targeting a stable release, but autocompletion will be bugged for users. If a new stable release is performed here, that would likely also fix the problem (but this fix might as well).

@Aerijo @50Wliu @damieng @atom Any feedback?

[damieng]

I left GitHub in the first quarter of 2018 and haven't touched anything Atom related since the end of 2018 when they officially killed Atom IDE off, sorry.

@atom Could we get this merged so it works on windows and a new release?
