If you are using Windows Vista or Windows 7 (as my writing this article) you may find a problem installing any software creates a service and need to interact with your desktop
Installation will silently fail and event viewer will report:
Service is marked as an interactive service. However, the system is configured to not allow interactive services. This service may not function properly.
There is a way to solve this. Take a look in your services.msc snap-in and identify the service named Interactive Services Detection. Now stop and disable it.
You have to reinstall the software needs to interact with your desktop and this time you will not get any trouble.
