There is a work around solution to this problem which Amazon and myself found while I was talking to their tech rep.
This only applies to an Amazon digital download as far as I know though it might be adaptable/applicable to other download sources.
This is a copy of the email the Amazon rep sent after the problem was solved.
Thanks for your patience and courtesy while we did troubleshooting for your "Divinity 2" game. I'm really pleased we actually got it to work. I've documented what we did to get it working and submitted it to our software engineers so hopefully this will help prevent a headache for someone else. Here is a copy for your reference.
Here is how it works.
1) Amazon Downloader puts 3 bin files and an extractor setup file onto the desktop.
2) The extractor setup file on the desktop is run, it extracts the game files into c:\program files\divinity II .
3) The final file to be extracted is an adobe file c:\Program Files\Divinity II\support\Adobe\AdbeRdr930_es.exe and it hangs.
4) If we cancel out of the setup extractor from the desktop because of the adobe freeze it will delete everything from c:\program files\divinity II leaving an empty folder.
5) Our fix was to use the task manager and kill the adobe setup and the desktop extractor before it got the chance to delete the game files from the c:\program files\divinity II .
6) task manager kill list:
As shown in #6 task manager kill list: above, you MUST kill/end the setup.exe FIRST as that is the Adobe installer.
Once you have clicked kill/end then you will have another application show up in the Task Manager named "unist" something or other. Sorry, I can't remember the name exactly as I killed it ASAP. This is the uninstaller that will remove everything except the game folder and a sub folder named "support" which Adobe would be installed in. Once that has been done you can kill/end the setupDK2.exe.
7) The desktop extractor will try to delete the game files, so we had to kill it's process before it got the chance.
All that is left is to start your game and enjoy.
I am running Windows7 64bit so my install directory tree is
c:\program files (X86)\divinity II.
XP users will have the same directories as above.
I can not say enough good about the Amazon rep. He is a smart guy. He stuck with an almost 30 minute phone call. He was interested in the problem and, what is more, was interested in the solution. As an older guy myself (54 years old) what impressed me the most was that he knows how to listen.
Well done young man, well done.
