I have changed from doing a stand alone munki Installer to using the autopkg recipes by moofit here https://github.com/autopkg/moofit-recipes/tree/master/Autodesk. the scripts will not be updated.
AutoDesk SketchBook Pro 2019 Munki Installer Make sure you check your product key and serial number they may have changed.
Put the Autodesk_SketchBook_for_Enterprise_2019_Multilingual_MAC_OSX.dmg into your munki repo packages folder
Put the Autodesk_SketchBook_for_Enterprise_2019-1.0.plist into the pkginfo folder
Edit the installer_item_location key to match the location and name of your .dmg
Add your serial number and edit the product key if it is different
