As the subject states, I am unable to upgrade deployments to the new version of Microsoft Deployment Workbench. I have many deployments that were created using the 5.x version. I recently upgraded to MDT 2012, version 6.x, and none of the deployments will open without upgrading them first. But I get the following message when it fails do upgrade:
Access to the path 'E:\Deployments\<name_of_deployment>\Deploy\USMT\x64\DlManifests\bitsextensions-server' is denied.
If I pull up properties of that folder, the Read Only check box is shaded. I can clear the check box and apply it to all sub-folders, but it just reapplies. When I pull properties back up the box is shaded again.
Does anyone know what causes this, and how I can resolve it?
