If installing the DataMart Client on Windows Server, you may encounter the following error, "Downloading failed with HRESULT=-2146697208".

  • The problem is likely to be caused by the 'Enhanced Security' option for Internet Explorer.
  • Turning Enhanced Security off and running the installer as the computer administrator will allow it to run properly.
  • Enhanced Security can be turned back on after the installation. This is the only time the default security settings need to be changed.
