I just switched to DNI 2.0 (220.127.116.11)
If I have some prerequisites to install, after they are installed, the GUI closes automatically.
If I run it on a machine where all prerequisites are already installed, The DNI never closes, it pops up and it stays open.
This is how the log ends:
2012-01-20 12:35:23 All components uninstalled, nothing to do.
2012-01-20 12:35:23 Extracting embedded files for component '*': NO FILES EMBEDDED
2012-01-20 12:35:23 --- Complete Command
2012-01-20 12:35:23 Executing complete command: msiexec.exe /i "D:\Install\Client\Client.msi"
2012-01-20 12:35:30 dotNetInstaller finished, return code: 0 (0x0)
This worked with my previous version (1.10).
