It'd require a very complex and error-prone heuristic to tell whether an executable is an installation package or not.
In general, the answer is no, you cannot do that.

A setup file could be created by anyone and is a program like any other. But you could probably find some common header bytes for the files if they are created by a popular installer program like Wise.
