I am new here and I cannot comment. So perhaps it is not an answer but rather workaround.
Firstly, i am not sure if scrapyd works on windows at all. Please see this part of Scrapy documentation.
Personally, I develop on the Windows but deploy on Debian (where couldn't find the scrapyd package at all at the time I was working on it) and noticed that performance of scrapy is considerably worse than on linux box, so you might reconsider your target. But I digress.
However, you don't need scrapyd at all. Scrapyd is just a wrapper that keeps running scrapy server in background. To get same functionality you can run from commandline (from the scrapy project folder):
scrapy server
The scrapy server would be then running as long as the commandline is running but you can workaround this with bat file and some software to running tasks in background. Hope it helps.
