Modify existing scheduled report - PC

Modify existing scheduled report - PC

I have an installation on a Windows Server with a similar problem as  Here but on Desktop Central.
It's a scheduled report that is emailed out to a user who is no longer in the company. I'd like to modify the report but I can't find it in the 'scheduled reports' section.
The report is labelled "Patch Vulnerability Database Report" but I'm not sure that is relevant to the issue.
There is only one login to Desktop Central, that is the admin login and this is the only report running.

The solution in the link above looks like it's for a linux install as the directories are not the same as on my Windows server, or maybe the directories have changed from 3 years ago.
Is there a way to either modify or delete a report that isn't listed in the reports menu?
Thanks
