Hi
I try to to upload nc.exe to Windows 7 via meterpreter but I get This error!

meterpreter > upload /root/Desktop/nc.exe C:\Windows\system32[*] uploading : /root/Desktop/nc.exe -> C:Windowssystem32
[-] core_channel_open: Operation failed: The system cannot find the path specified.

Any one know why?

I will be thankful for answer.
