Windows installer - Zotero 7 - Missing valid signature, unkown publisher

I was trying to install Zotero 7 with the setup exe today. However, upon clicking on the file a windows security warning pops up:
"The publisher could not be verified. [...]"
"Unkown Publisher"
"This file does not have a valid digital signature that verifies its publisher."

Where did you download Zotero from? What's the full filename?

The .exe from our site has a valid signature.

Zotero-7.0.11_x64_setup.exe

and from: https://download.zotero.org/client/release/7.0.11/Zotero-7.0.11_x64_setup.exe

That's a problem with your Windows installation. You're missing some intermediate or root certificates.

(And you're running some endpoint-protection software there, so obviously this is a customized Windows installation. You should talk to your IT department if you're having trouble.)
