I tested With "Divinity Original Sin: Enhanced Edition" works fine. Good job bro.
If you want to use Divinity Original Sin: Enhanced Edition, create Setup.ini for commonredist file.Or download attachment decompress in DOS_1
Code:
[Launch1]
Name=Visual C++ 2013 x86
32Exe={src}\_CommonRedist\vcredist\2013\vcredist_x86.exe
Argument=/s
BeforeInstall=0
[Launch2]
Name=Visual C++ 2013 x64
64Exe={src}\_CommonRedist\vcredist\2013\vcredist_x64.exe
Argument=/s
BeforeInstall=0

Note: Compression or Install time, depends of your hardware
But some time UltraArc has finished job, not all files. I think small mistake for UA.
And smallinstaller need be fix. It caught my attention.(marked areas)
