Get-ScheduledTask error on local environment with PSVersion 4.0

I can not execute Get-ScheduledTask command by local environment.
However I can execute it to remote servers from local environment.

Command(to remote servers)

> $c = New-CimSession -ComputerName "host name" -Credential xxx.xxx.xxx.xxx
> Get-ScheduledTask -CimSession $c -TaskName "taskname"

Command(to local)

> Get-ScheduledTask

Questions
1) What is the cause of this error?
2) Why I can execute the command remotely?

Please let me know if you need more information to solve this issue.
Thank you.

The command can not execute on Windows7.
