All client computers on your company network were recently migrated from Windows XP to
Windows 7. Your company uses a proprietary application that is currently not compatible with
Windows 7. A shim has been created and applied to mitigate compatibility issues until a Windows 7-
compatible version is developed. A security update is made for this application. The update must be
tested and then deployed as a new version of the application. During testing you are unable to install
the application. You need to ensure that the application can be installed in the test environment
before it can be deployed to the production environment. What should you do?

A.
Disable UAC prompts.

B.
Run the .msi file from an elevated command prompt.

C.
Modify the shim to apply to all versions of the application.

D.
Modify the shim to apply only to the new version of the application.

Explanation:
Answer is D. Different software versions require different shims.
