If it’s an executeable with dependencies in the archive it might not run without being unpacked.
The greentext says “he asks for some files”, that doesn’t sound like an executable, which usually gets blocked by the mail system anyway (even in a zip, if there’s no password on it).
But yeah, that is one way to have it broken, besides Windows refusing to run a random .exe
Outlook blocks it by default so if you allow exe’s to be emailed… you’re pretty stupid.
