This is a VERY old topic. But I wanted to add my findings as I did not see an answer elsewhere.
You must look at the Adobe installer log file which is in the following locations:
- Windows 32 bit: \Program Files\Common Files\Adobe\Installers\
- Windows 64 bit: \Program Files(x86)\Common Files\Adobe\Installers
- Mac OS: /Library/Logs/Adobe/Installers/
Extract the gz file type to view the log file.
For my case, there was software running which was preventing the installation from completing.

Hope this helps anyone in the future.
