VMware VIX\vmrun.exe - Error: Unknown error

I have Vmware Server 2.0.2 on Windows Server - I installed VMware VIX and I tried to start virtual machine from command line useing this:

"C:\Program Files (x86)\VMware\VMware VIX\vmrun.exe" -T server -h http://localhost:8222/sdk start "[standard] Win2008R2Trial/Win2008R2Trial.vmx"

and it returns

Error: Unknown error

I tried to open page http://localhost:8222/sdk and it doesn't exist - maybe it should be enabled or something like this?

I can sucessfully open page: http://localhost:8222/ui/

Any idea?
