vBulletin Connect v5.4.0 Final Release NULLED

I don't suppose any one knows how to get this working with iis i always get admincp not found

iis 10.00
php7.2 , php7.1 and php5.3 all have fastcgi
iis rewrite is installed

site is ssl

the funny thing is i had it working but had to reinstall iis because of messing up a client cert setting

website is is in a subdomain

i think it is to do with the web.config file and baseurl in config.php

if anyone can shed some light this will be great because even the front page is not loading correctly
