Client machines waiting for content

Question

Hi - I have deployed a couple of applications that never seem to deploy to clients
This does not happen with every application so I don't think its a problem with connectivity / communications anywhere. 
My clients are pointing to the correct management points and site. 
Application content has been successfully distributed to my distribution points 
My Distribution Settings tab on the package is set to "Distribute the content for this package to refereed DP's" and to "Automatically download content when packages are assigned to DP's"
My Content Locations tab on the package has the correct distribution point
Distribution types content tab has the correct content location and deployment options is set to "Download content from DP's and run locally"
Distribution types Programs tab has the correct installation / uninstall parameters
Distribution types Detection Method is set
Distribution types user experience set to install for system and installation probably hidden. I have tried with different logon requirements and still get no where
Deployments Properties content shows the right DP
Deployment Properties Deployment Settings action Install and Purpose Required. Also checked is allow clients on a metered internet connection
Deployment  scheduling based on client local time
Deployments User Experience set to display in software center and show all notifications
Commit changes at deadline or during maintenance window is set
Alerts is set to create a deployment alert when the threshold is higher than 0
Content is distributed and deployed to a valid machine collection with valid machines pointing to the right site
Monitoring > Deployments  shows waiting for content 
I can manually install the apps OK.

Please check the client log files for more information. For example log files like
execmgr.log, LocationServices.log and CAS.log.
