Guest operations Get processes Permission denied

Hi,

I'm trying to execute some commands on a VM using Guest operations.

When using "Run program in guest", it seems to works: I can create a folder on C: with cmd /c md C:\folder.

But when I try to get the processes (in order to get the result of the command I ran), the workflow fails with the message: Permission to perform this operation was denied.

It's the same wether I use the local Administrator account or a domain account with administrator rights.

I have the same message when using the "Create temporary directory in guest" workflow.

Any idea or pointer?

Thank you,

Jonathan
