Yes, Adobe released new update for the most powerful RIA development tool. What will happen next? yes, we download and install it. So what will happen next with your exist Adobe AIR project? got the error like this when you try to compile both in release and debug mode.

ERROR #1014: Class IIMEClient could not be found.

The easiest way to solve this problem is described below:

  1. Go to your <application-name>-app.xml
  2. Replace your Adobe AIR version in this line: 
    <application xmlns="http://ns.adobe.com/air/application/1.5.3">
  3. With this line: 
    <application xmlns="http://ns.adobe.com/air/application/2.0">
  4. Save and re-compile your application.

Thank you for your interesting and cheer!
