Hi @BEKEDE ,

I have a couple of suggestions to resolve this issue.

1. Add the server path to the Intranet security zone on the browser to resolve the mismatch.
2. If the ethernet connection of your computer is set as a public network Please change it to a private one, which changes trust and security levels for network applications among other things.

After that please try to install it. (Please note that IE is the recommended browser to install any BR related software. If you have used any other browser for this, please  uninstall pre-requisites and BR client and re-install all the software and test the application)

Best Regards,

Thiwanka
