To open the reports in TIBCO Spotfire Web Player, you can copy the "Web Client URL" from the TIBCO Spotfire Analyst client. When you open the Web Client URL in a browser, the admin console login page appear prompting for authentication (if there is not an already authenticated session), and once authenticated, the analysis will open.
You may receive a 404 error if the case of the Web Client URL has been modified. When you access the Web Client URLs in a browser using VIEWANALYSIS or OPENANALYSIS in upper case as shown below, the Web Player URL does go to the authentication log on page, but instead of opening the analysis, a 404 error will appear after logging in. So the analysis will not be opened when you use uppercase for VIEWANALYSIS or OPENANALYSIS since the VIEWANALYSIS/OPENANALYSIS is given in upper case which is the name of a ".aspx" file.
