Running executables in the Windows Temp folder

Hi, I'm not a programmer so not terribly familiar with best practices for Windows programming. But what I am trying to do is vet a software program. And what I'm trying to find out is if there are any concerns with an executable running in the Windows Temp folder with administrative privileges.

This program puts agents on remote workstations. It creates the executable in the Temp folder and then runs it.

Now my understanding is that the default set up for the Temp folder is to restrict access (Windows XP, Vista) for local users. Would another installed program such as malware be able to manipulate the agent program to run at elevated privileges? What would prevent that?
