Here's what I've done to deploy Reader DC to a test machine so far:
-Apply for the Distribution License, Get the approval email, Download the .exe (Windows 10) from the email link provided. (https://get.adobe.com/reader/enterprise/)
-Extract the .exe into it's pieces (msi, msp, ini(2), exe, cab) into a directory let's call "AcroRD21_007"
-Copy AcroRD21_007 folder to a Network share, let's call it "\\SHARE\Deployables\"
-Downloaded/Installed Acrobat Customization Wizard DC
-Within the Wizard: File>Open Package \\SHARE\Deployables\AcroRD21_007\AcroRead.msi
-Make my changes, Transform>Generate Transform.
-Verified Setup.ini has the changes:
-Configured the GPO with the help of this link: (https://www.adobe.com/devnet-docs/acrobatetk/tools/DesktopDeployment/gpo.html). Ensuring that I specified the Transformation file created by the Wizard (AcroRead.mst)
-Assigned the Policy to the OU my test machine is in.
-Forced gpupdate on target machine.
Initially, without going through all these steps, I could get the .msi to deploy to the target machine, but it was only 2015 version, and any attempt to upgrade would prompt an "Error: 111100". I suspected I needed to learn more about these .ini files. That's when I stumbled upon the Customization Wizard.
Now I'm exactly where I started. It installs 2015 version, with no ability to upgrade. Same Error. What am I missing?
Each attempt at installing is to a clean target machine (never had Adobe installed).
All input is appreciated.
