Issue:
Attempting to install APM Standalone PP for Web Servers on Windows 2016 - after running for a few seconds it quits with an error. Looking at the details, you see text similar to:
Get error Flexeraax2$aaa: Windows DLL failed to load
at Flexeraax2.af(Unknown Source)
at Flexeraax2.aa(Unknown Source)
Environment:
Windows 2016
Cause:
Some configurations of Windows 2016 can cause fatal problems for the PP for Webservers installer.
Resolution:
The installer is only extracting files from an archive - all steps after that are manual.
Run the installer on a different system, then copy the resulting folder to the target server to continue the installation.

From what I have seen in my own environment InstallShied creates a directory under directory %TEMP % with name Innnnnnnnn to hold its temporary files.
Hope that helps
