That‘s crazy.I mistakenly uninstalled zotero, and I want to reinstall it ,but it happens to be incredibly long wait and it seems takes a lot of disk space, how to solve it?

You should cancel that if it's still going, manually delete C:\Program Files\Zotero and C:\Program Files (x86)\Zotero if they exist, restart your computer, and try again.
It's possible that something else on your computer (security software, malware) is interfering.
