Users are unable to install “Structural Synchronizer V8i version 08.11.09.130”, getting a message that indicates, "Check internet connection and restart the setup or provide proxy settings".
The Structural Synchronizer 08.11.09.130 installer tries to install several Microsoft components through an internet connection. If your system cannot reach the Microsoft domain in order to install these prerequisites, then the installation will stop.
One solution is to manually install all of the prerequisites, but those installations still must be obtained from Microsoft’s website.
Alternatively, Bentley Technical Support can send a very large installer with all of the prerequisites built in.
