Self-updater not working on slipstreamed MSI deployments
So I received a distribution license to deploy Acrobat Reader DC to the computers in my company. I am doing so using a Group Policy in my Active Directory domain. I managed to create a Software Installation policy and have it install AcroRdrDC1500720033_en_US.msi. However, as there are no MSI files after 2015 (only MSP files), I decided that I would just slipstream the MSPs into the MSI so that I can directly install the latest version. I was able to create the admin install, patch the files, and recreate a patched MSI file. It installs normally, even through Group Policy. However, anytime there is an update for Reader DC, it will fail to update itself. It gives an Error 1603, Fatal error during installation. I assume this is because it is looking for the original (1500720033) MSI file (possibly for certificate/hash from Adobe), but can not confirm.
I can continue patching the MSI files everytime there is an MSP, but to install the update, the computer will need the be rebooted. Is there a reason the built-in Adobe Updater will not update a slip-streamed MSI file? Is there another way to install an updated version, so that it can keep itself updated?
I can go back to using the original MSI file if needed, but would prefer to know that everything is updated and secure in a single install instead of waiting for the program to hopefully update itself. I'm sure I can write a script to install the patches and deploy that over GPO, but would prefer everything encapsulated in a single MSI (which I already have).
