When installing Quickmap, you may get this error:
Unable to install .Net Framework: The operation completed successfully
This can happen if .NET Framework fails to install during the Quickmap installation. Often this can happen if you are installing onto a Server operating system (such as Microsoft Server 2016), as Server OS requires .Net to be installed as a Windows Feature.
To fix the Unable to install .Net Framework error, download and install .Net Framework 4.6.1 or above, then retry the Quickmap install.
