Class IIMEClient could not be found

Are you getting this error in your Flash Builder 4 environment?
VerifyError: Error #1014: Class IIMEClient could not be found.

Fret no more. Change the following lines in your name-app.xml:

From:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<application xmlns="http://ns.adobe.com/air/application/1.5">

To:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<application xmlns="http://ns.adobe.com/air/application/2.0">

For those who cannot see the difference; I replaced the xmlns version number. If you would like a more in depth walk through then please go here.
