the system is a fresh installed Windows 8.1 Enterprise system in a virtual machine. There is except of a text editor no other software installed and the updates of Windows are all done.
When I compile the project (uncompressed), one of the CPU cores goes up to 100%.
I managed the problem by creating a 7zip archive and integrating this archive. But it is a lot of work to get this to work.
What is InstallAware doing when the process windows tells "Built plug-in action File Bag"?
the 7zip archive is created with a Compressed build and not when generating an uncompressed layout ( ... this because you said to use an uncompressed build with your first post).
Anyway the 7zip archive generation is one of the latest steps during a File Bag build process. As first, the process tries to create the File Bag directory layout structure and its files under release folder. This is the reason why I suggested you to verify if something else could interfere during this phase.
my workaround using a manually created 7zip archive is a bad workaround - I had to rewrite parts of script includes too. Without that I could not manage to create any installer: wether compressed nor uncompressed.
I just reproduced the problem with these steps:
> Create an empty Basic Setup
> Select "Microsoft SQL Server Express 2014 /x86 and x64 WOW)
> Build as "CD or DVD"
Now the process mi.exe runs on 100% in its core.
The destination folder grows by 300kb per Minute ...
I just repeated your steps using my test machine and it takes no more then 15 seconds to compile (CPU 16%).
Please note that I am using a physical machine (Win 7 4 Gb Ram) and not a vm environment.
A VM environment should never be used in development/production stage.
BTW, I have personally noticed performance degradation using VM machines where for example and for test purpose only, I have tried to install Visual Studio.
Furthermore, I have noticed that this is much more relevant when the latest OSes are mounted on the VM.
