XFA forms are wrapped with a shell PDF which is the only thing a PDF-processor sees when it doesn't support XFA.
The preview in Windows explorer doesn't know about, so you only see the Please Wait message.
Unfortuantely this problem is forcing us to NOT be able to use LiveCycle forms altogether!!
It is so frustrating when adobe technology doesn't work with adobe technology...we pay alot of money for these programs and you'd think we could at least get the programs to be compatible with each other!!
LiveCycle ES3 doesn't have support for Acrobat XI, Windows 8. Ref. : http://help.adobe.com/en_US/livecycle/10.0/supported_platforms.html
Although they are supported with ES4. Ref. : http://helpx.adobe.com/livecycle/help/livecycle-es4-supported-platforms.html
Hope this helps.
