There are two versions on the computer after the update.
After I updated from 7.0.15 to 7.0.16, both versions of the program are now present on my computer, taking up a lot of memory. Can I uninstall 7.0.15? Will it affect the normal use of 7.0.16?

I'm not sure how you ended up with two — that generally shouldn't be possible. You should uninstall both and reinstall the current version of Zotero (7.0.24) from the download page. Your data won't be affected.
