Hi,
If I click on the link you provided, and go down to Duo Desktop, and in the "Windows 10 and Later" section, there's a white "Download" button right below the SHA-256 checksum, which will download an MSI package.
(See screenshot attached/below.)
Additionaly, for many (all?) DUO downloads, there's also a -latest link available.
So currently, instead of using https://dl.duosecurity.com/DuoDesktop-6.12.0.msi (which will get you this exact version), you can also use https://dl.duosecurity.com/DuoDesktop-latest.msi , which will give you the latest version (currently 6.12.0).
Using the -latest link you don't need to find a new link every month.
