The "Grant Offline Exception" button got me around the eternal AdobeID sign-on window.
Unfortunately, the product doesn't want to install silently using the transform generated by the Acrobat Customization Wizard DC. Keep getting an error 1603. I've tried installing using "msiexec /i AcroPro.msi /q TRANSFORMS=transform.mst" as well as using msitran to transform the AcroPro.msi file and use "msiexec /i AcroPro.msi /q".
Anyone encounter that particular error using customization transforms?
