No, it isn't wrong, since you are using mapped drive, which may not exist in a
different user session.
There's an easy solution, though: stop using mapped drives. You should have
been, for 17 years now.

Store setup.exe on the same network share and use UNC path to access it.
Then "other people" could use both a fresh package cache and a fresh setup.exe
You can even restrict write access to the share, if desired, then "other
people" could use it to install from downloaded archives, and selected
administrators with write access could refresh package archive.
