vmrun fails on ESXi 4.1

I need to use only one simple command, but it unfortunately ends up with error on ESXi 4.1. The command is:

vmrun -T esx -h "https://x.x.x.x/sdk" -u root -p ****** stop "[Datastore] New Virtual Machine/New Virtual Machine.vmx"

Error: The virtual machine is not powered on: New Virtual Machine/New Virtual Machine.vmx

I tried these builds: VIX API 1.10 Beta, VIX API 1.8.1, VIX API 1.6.2 each without success

On ESXi 4.0 was everything fine and VM is really powered on

Can anybody help?
