FYI, I encountered this error running a deployment for one of our projects using the AppVeyor agent:

Import-Module : File C:\Program Files\AppVeyor\DeploymentAgent\agent-api.psm1 cannot be loaded. The file C:\Program Files\AppVeyor\DeploymentAgent\agent-api.psm1 is not digitally signed. You cannot run this script on the current 
system. For more information about running scripts and setting execution policy, see about_Execution_Policies at
At line:48 char:1
+ Import-Module 'C:\Program Files\AppVeyor\DeploymentAgent\agent-api.psm1'
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : SecurityError: (:) [Import-Module], PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess,Microsoft.PowerShell.Commands.ImportModuleCommand
You can view the deployment here:

The server's execution policy is set to 'Unrestricted' (meaning when I start powershell and run 'get-executionpolicy' it says Unrestricted), so I think it might be a problem with the session that the AppVeyor Agent sets up for itself.

The problem disappeared the second time I ran the deployment.

    What OS is that? Does agent service run under LocalService or a different account?

    Have you tried switching agent service to use administrator credentials instead of Local System?
