PKT file doesnt open on other OS

[markymark]

I'm currently using windows 11 and packet tracer version 8.1.1.0022. When I send the file to my teacher or anyone on windows 10 it says the file is not compatible with this version of packet tracer. Both are using 8.1.1.

Usually error "not compatible with this version of packet tracer" relates to PT version;  maybe there is newer version than  8.1.1.0022 or I have older PT version

can u attach PT file here for us to check (must be zip format); note if file come from windows 11 or 10
