How safe is this?

I need to modify setup behavior for various programs. As I can't modify the setup files, directly, I've made setup "launchers" with AutoIT. Meaning I have renamed the original Setup.exe into Setup.dat, and I'm launching it with Autoit "Setup.exe" via Run command. Of course my AutoIT script asks for Admin rights on run.

But I'm still a little cautious about this whole idea... Are there any side effects of this? Will the original file (Setup.dat) perform Admin-requiring tasks properly if I run it with Admin-requiring AutoIT script? It's not an EXE anymore, and I'm not sure if it will behave as EXE with Admin rights should.

Pardon me if it's not an entirely AutoIT-related question.
