Thanks @andykn101 for giving me something to go on.
I guess this is what I get for using Adobe's tools to package their installers :(
I see now in my registry where it's looking for source path in the local software delivery folder (I searched for acroread.msi or acropro.msi and see sourcelist folder listing softwaredelivery folder path).
Anyone have any feedback on downsides to running 'updating source path of windows install applications' using the built in source path update for all windows install apps?
I did this on a test machine and see it updated the sourcelist folder in registry to my CMS server & the adobe patches installed properly.
Could this mess up locally install programs somehow? I checked office (installed on the image) and it seems like in registry the source list looks ok still on the test machine.
I would prefer to just update the 2 Adobe app source locations, but when I right click on the package in software catalog and do update source, it runs on another test machine without error, but source locations in registry didn't change on the client. It also seems like doing it this way you can't schedule it to run and would only hit computers that are powered on?
