Return code from the Adobe Installer Process is (7).Stopping the installation process.

I used the latest CreativeCloud Packager to package the latest Acrobat Pro DC (Continuous) version for my organization - 18.9.20044. The package installs fine on my 2 personal PCs, but when I try to run the install on another PC, I get this message:

It's a Windows 7 Enterprise Service Pack 1 x64 with Office 365.

I followed all the tips to fix the issue mentioned here: Errors "Exit Code 6" and "Exit Code 7" installing Adobe CS6, CS5.5, CS5, Premiere Elements, and Photoshop Elements including repairing/reinstalling Visual C++ Redistributables (2005, 2010, 2012, and 2015).

Here is the PDApp.log file:

Thanks so much if you can point me in the right direction!
