I mean, at least tell them what the correct usage is.

OP, you probably want “software package” or “a piece of software”.

“Software” is a mass noun, like “butter”. You can’t have “a butter”. You can have “a pound of butter”.

Usage notes

Software is a mass noun (some software, a piece of software). By non-native speakers it is sometimes erroneously treated as a countable noun (a software, some softwares).
