I've got the same problem. I used the CPP to create silent setups for Acrobat DC and Photoshop. I then ran the exception deployer (in pre-install mode), the MSI and the exception deployer (in post-install mode). When I start Acrobat DC, I'm getting the "sign into Creative Cloud" popup. We've got an educational license, our students/teachers don't have to sign in to CC.
What's the fix?
