Hello,
Adobe Digital Editions Version 2.0 does not support Flash-based multi-media objects. However, version 1.7 did supported it.
You may try installing vesion 1.7 from http://tinyurl.com/diged172
or http://helpx.adobe.com/digital-editions/kb/cant-install-digital-editio ns.html
Hope this helps in answering your question.
Regards,
Sharad
