Before installing the Reporting Web Viewer ensure that all requirements have been met. See Requirements.
To run the Reporting Web Viewer installer from the command line, it must be launched using this command: msiexec /i "Hyland Reporting Viewer x64.msi" ADDLOCAL=ReportingViewer.
By default the Web Viewer is installed to C:\inetpub\wwwroot\ReportingViewer\. To change the installation location, set the REPORTINGVIEWER_FILES property on the command line. For example: msiexec /i "Hyland Reporting Viewer x64.msi" ADDLOCAL=ReportingViewer REPORTINGVIEWER_FILES="C:\My\Install\Directory".
If you do not include the REPORTINGVIEWER_FILES property the Web Viewer is installed to the default location.
The installation location entered is configured under IIS as a virtual directory for Internet access to the Reporting Web Viewer.
For details on additional properties for command-line installations see Property Names.
