Where are the files saved?

[gearcapitan]

There is nothing in the avet folder !!!!!!

A more exact description may help !!!!!!
But anyway, guessing is also fun, so you may execute one of the build scripts, eg.:
./build/build_win32_meterpreter_rev_https_fopen_shikata.sh
from the avet directory and send the output.

In the avet folder, as said in the script. If you want further help please take the steps I explained before.
