Applying latest security update to Acrobat DC

We have Acrobat DC installed to multiple windows systems deployed via SCCM using a creative cloud MSI built from the Adobe Creative Cloud Packager.

Now we'd like to apply the latest security "APSB17-01: Security Updates Available for Adobe Acrobat and Reader" but to do that appears to require the original msi to apply the update to. Trouble is we don't have that "Acrobat_DC_Web_WWMUI.exe " as it did not come with the MSI created by Adobe Creative Cloud Packager.

Anyone know where can we get the original from?
