subprocess.call with rpyc throwing error

I am using RPyc to execute commands on remote machine. I am getting error when I run the following code:

cmd = ['clonetst.exe', 'C:\\Users\\pqalinux\\Desktop\\Flowcontrol.tst', 'C:\\Users\\pqalinux\\Desktop\\lst_20150819_110008.lst', 'C:\\Users\\pqalinux\\Desktop\\tst_20150819_110008.tst']
self.host = rpyc.classic.connect(self.ip)
StatusCode = self.host.modules.subprocess.check_call(cmd)

The remote traceback is:

Failed to create tst file: [Errno 2] The system cannot find the file specified

========= Remote Traceback (1) =========

What might be the problem? Any ideas?

Either 'clonetst.exe' is not installed on the remote machine or it is neither on the path nor in the current directory. Make sure it is installed and either add to the path permanently or in the environment dictionaries.
