AdWords currently supports only Adobe Flash Player versions 4 through 10.1. If your ad uses any other version (such as 10.2), it cannot be uploaded.

You should see an option to preview a non-Flash version of your ad when you upload a Flash file. Don’t see this option? Make sure your SWF file uses ActionScript 2.0 and avoid filters or blending if possible.

Flash ads must support the clickTAG variable and the only user interactions that are allowed to be tracked are clicks.
