Your network contains an Active Directory domain. The domain contains 3,000 client
computers. All of the client computers run Windows 7.
Users log on to their client computers by using standard user accounts.
You plan to deploy a new application named App1.
The vendor of App1 provides a Setup.exe file to install App1. Setup.exe requires
administrative rights to run.
You need to deploy App1 to all client computers. The solution must meet the following
requirements:
App1 must automatically detect and replace corrupt application files.
App1 must be available from the Start menu on each client computer.
What should you do first?

A.
Create a logon script that calls Setup.exe for App1.

B.
Create a .zap file.

C.
Create a startup script that calls Setup.exe for App1.

D.
Repackage App1 as a Windows Installer package.

Windows Installer features Diagnoses and repairs corrupted applications–An application can
query Windows Installer to determine whether an installed application has missing or
corrupted files. If any are detected, Windows Installer repairs the application by recopying
only those files found to be missing or corrupted.
