First, let's install all the required prerequisites before installing Starry Night. Otherwise, Starry Night will run with full UI to install prerequisites.
Microsoft Visual C++ Redistributable for Visual Studio 2012 x86
You can install Visual C++ Redistributable silently by running "vcredist_x86.exe /passive".
.NET Framework 3.5
Only need to enable .NET Framework 3.5 for Windows 8 and 10. Simply run "dism /Online /Enable-Feature /FeatureName:NetFx3 /Quiet".
Also, make sure you have at least Internet Explorer 9.
Now we have all the prerequisites installed. Let's install Starry Night.
If you want a progress bar during installation, run starrynightcollege8.exe -s1 -sp" APPDIR=""C:\Users\<username>\"
If you want no UI at all, run starrynightcollege8.exe -s1 -sp" APPDIR=""C:\Users\<username>\"
