RETScreen is a software program developed by Ressources Naturelles Canada. It adds registry entry for the current user which will allow the program to automatically start each time it is rebooted. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The setup package generally installs about 26 files and is usually about 838.5 KB (858,624 bytes). Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows XP. While about 45% of users of RETScreen come from the United States, it is also popular in Canada and Spain.
