Here's what you need to do to deploy Starry Night (or any msi installer) to client computers via GPO.

1. Get the MSI package

•  Extract starrynightcollege7.exe using 7z or WinRAR

2. Create a distribution point

• Log on to the server as an Administrator user
• Create a shared network folder (this folder will contain the MSI package)
• Set permissions on this folder in order to allow access to the distribution package
• Copy everything that was extracted in Step 1 to the shared folder

3. Create a Group Policy Object

• Click on the Start button, go to Programs, select Administrative Tools and then select Active Directory Users and Computers
• Right-click your domain name in the console tree and select the Properties context menu
• Select the Group Policy tab and click New
• Set the name of the policy (for example StarryNightCollege)
• Click Properties and select the Security tab
• Check the Apply Group Policy checkbox only for the groups to which the policy will be applied
• Click on the OK button

4. Assign an MSI package

• Click on the Start button, go to Programs, select Administrative Tools and then select Active Directory Users and Computers
• Right-click your domain name in the console tree and select the Properties context menu
• Go to the Group Policy tab, select the object you want and click Edit
• Expand Software Settings under Computer Configuration
• Right-click Software Installation, select the New context menu and then click on Package
• In the Open dialog type the full UNC path of the shared package you want to assign
• Click on the Open button
• Click on Assigned and then click OK (the package will be added to the right pane of the "Group Policy" window)
• Close the Group Policy snap-in, click OK and exit the Active Directory Users and Computers snap-in
• When the client computers start, the assigned package will be installed automatically
