I built an installer. but the files are ex-tractable by reverse engineering . My  understanding is hackers can use this way to extract and modify the features / inject malicious scripts .

how to prevent the files are ex-tractable by reverse engineering

This may be a better question for the InstallShield forum, but I would say that it is quite common for a single file setup to unpack itself to a temp directory for execution. The installer itself may be signed with a trusted certificate to confirm it hasn't been tampered with prior to execution via system policies.
