I receive the following error when trying to install mediawiki with installatron in a subdomain that is a subdirectory of my primary drupal install. I do however have an .htaccess rule that allows you through to said subdirectory, that was tested successfully as well.
This is the error:
#####################################
! A test of the selected domain has failed (HTTP error: 403).
Installatron is unable to install on a domain that is not resolving/loading to this web account.
If this is a new web hosting account, or if this is a newly registered domain, please allow up to 24 hours for the domain to begin working (though usually within a few hours).
If you're sure that the domain is correctly loading to your web account, contact your web hosting administrator.

I have removed my personal details from this error however I can tell you that the A record is aimed at the right IP and does resolve via dig and multiple DNS servers.
