working with .zip to .exe converters

I have two files one is firefox.exe and the other one is trojan.exe i also have a .zip to exe converter ,whenever you click the modfirefox.exe which i have createn that contains those two it automatically unzips itself to "c:\program files\mozilla firefox\" then run firefox.exe & trojan.exe but my problem is that it can only run one program is there any way i can solve it???

EDIT: i know that i can create a file (file.exe) that will open those two since i know there location but its a waste of space and time…

This is on the same topic as your previous thread; in the future, do not start new threads for that. In your previous thread, you were told that the solution would be to Google "file joiner" and peruse through the results to find one that works for you. A zip to exe converter most likely makes it a self-extracting zip file.
