If you are sure the software package you are installing IS genuine, if you trust Duncan does not want your secrets, if you got it directly from Duncan's site, on a legitimate network connection, then just say "Install darnit!"
Last week I had a new Win10 and installed Office 2003 and PSpice 1999, and a lot of other stuff Win10 never expected to see.
Windows has several errors. Files downloaded from the internet won't run without intervention; you can poke file Properties and un-check that. And program installers usually raise a warning, but you expect that.
Apple wants to protect its users AND its business, so mystery files make it upset. Specific advice for Macintosh Gatekeeper warnings/blocks:
Trend Micro is a well known antivirus shop. Their general strategy includes running A-V on any file of uncertain origin. Since you know who and where your PSUD installer came from, that seems excessive. You know the file is OK, and it is reasonable that Apple can't track (or can't remember) every program out there.
