No need for an installer when it's just one file you can run anywhere. And folders/zips are way too hard for the average user. Ask me how I know. My partner gave up an entire game platform because it was delivered as a .7z file they could not figure out.

But a .7z requires a custom expander, .zip is natively supported by windows, isn't it?

.7z recently got native support.
