Troubleshooting Microsoft .NET Framework Installation

While installing the GeoHECRAS software on a computer workstation running Windows 7 Service Pack 1 operating system, the application fails to install the Microsoft .NET Framework along with the GeoHECRAS installation and displays the following error message.

This issue may occur if the required trusted root certification authority (CA) certificate is not installed in the Trusted Root Certification Authorities store on the client computer.

This issue can be corrected by installing the certificate manually in the Trusted Root Certification Authorities store of the client’s computer.
