Upload the file(s) to cloud.acrobat.com/send using the instructions at How to share a file using Adobe Document Cloud , or post the file(s) to a file sharing service of your choice that doesn't require user log on to access. Post the link to the uploaded file(s) in your reply.
How, exactly, does your organization deploy the Flash Player to the client?
What permissions to the end-users have?
The deploy is done through a GPO with the msi flag "/passive".
I have tried with end-users with administration permissions and without them, the result is the same.
