Resolution

This problem usually occurs because an older, unsupported version of .NET framework is installed on Spotfire Node Manager machine. Lead Discovery Premium 2.0 requires Microsoft .NET Framework 4.7.2 or higher.

To resolve the problem, download .NET 4.7.2, or more recent version, and install it on Node Manager machine. A full machine OS reboot will be required, but no further configuration changes will be necessary. After reboot, Web Player service should start without any errors.

Note: similar issue might occur on end user's machines that run Spotfire Analyst client with Lead Discovery Premium 2.0. In most cases, updating .NET version will resolve the problem.

If you're still seeing this or similar errors after updating .NET, please contact Support for assistance.
