HomeKit integration wont set up - Windows 7

Hi. I am trying very hard to get my Home Assistant smart devices to work with Siri and the Home app on my iPhone 8. When I type in homekit: in my configuration.yaml, Home Assistant sends me a notification saying

INVALID CONFIG:
The following components and platforms could not be set up:

homekit

Please check your config.

I think I am doing everything right. I only used homekit: but I also tried using the entity filter and nothing works. I have been using Home Assistant for a month now, so I am still fairly new to this. Can I please have help? I seem to be the only one with this problem.

Thanks,
