An 'Access Denied' error usually indicates that the user (or service account, if using a Recast Proxy) attempting to run Right Click Tools actions does not have local administrator access on the target computer.
Resolution
There are two options for resolving the error:
Make sure that the user running the action in the Configuration Manager console has Local Administrator permissions on the target device. If Local Administrator access is not allowed for certain users, a Recast Proxy can be configured to run the actions as a service account.
If named user accounts do not have Administrator Access to computers, you can also resolve access issues by installing a Recast Agent on a device. Each agent must be installed separately, configured to run actions and authorized in the Recast Management Server interface.
