This tool compares a targets patch levels against the Microsoft vulnerability database in order to detect potential missing patches on the target. It also notifies the user if there are public exploits and Metasploit modules available for the missing bulletins.
I fixed the problem with xlrd, by replacing it with openpylx. It is a bit slower, but works without a weird workaround. I also upgraded to python3.
