The APSCN Plus is an application used in schools. The support and everything related to troubleshooting, documents, and other problems are handled by the local administrator or by the support technicians assigned to your school. Unfortunately, I can't say the exact method to install it since no information is provided about its distribution package, platform, etc.
The official website doesn't provide a way to contact the developer/support team, therefore you need to contact the local administrator.
