Comments and improvements welcome

Tested with opsi 4.0.2
Tested with opsi-winst 4.11.2.6 - 4.11.3.2
Tested with Windows XP Professional and Windows 7 (x86/x64)
dotnetfx is needed, so make a dependency
You have to deflate the original setup.exe (Eraser 6.0.10.2620.exe) (use 7-zip) to get the msi files.
