I've had a number of people having issues starting the LiveCycle feature in sharepoint 2010 here is the workaround
I had to do the following, download the powershell script located here https://skydrive.live.com/?cid=3d1aa7b9ba4b05fd&resid=3D1AA7B9BA4B05FD !234&id=3D1AA7B9BA4B05FD%21234
Go into powershell, that’s done by running powershell.exe just like you would a cmd prompt
When at the powershell prompt issue the command Set-ExecutionPolicy AllSigned
Issue a cd to go to the directory that contains the download script
Then issue .\Set-RemoteAdministratorAccessDenied-False.ps1
This is a known issue. See the blog http://blogs.adobe.com/livecycle/2012/05/access-denied-sharepoint.html
