Description
After installing Spotlight on SQL Server Enterprise, It cannot connect to the Diagnostic Server installed and specified in the installation dialogue during the wizard process.
The GUI shows:
"No server found on the specific host"
Checking the event viewer, there is an error:
Stopping Diagnostic Server. catastrophic error occurred failed to initialise Diagnostic Server runtime environment : PicoLifecycleException: method 'public abstract void org.picocontainer.Startable.start()', instance 'LicenseServiceImpl[LicenseService, started=false], Failed to start LicenseService : Command '"D:\Program Files (x86)\Quest Software\Diagnostic Server\Agent\ext\QKT.exe" 44 "Spotlight on SQL Server Enterprise" read' failed : [128] : Failed to start LicenseService : Command '"D:\Program Files (x86)\Quest Software\Diagnostic Server\Agent\ext\QKT.exe" 44 "Spotlight on SQL Server Enterprise" read' failed : [128] : Command '"D:\Program Files (x86)\Quest Software\Diagnostic Server\Agent\ext\QKT.exe" 44 "Spotlight on SQL Server Enterprise" read' failed : [128]

Cause
There is no .NET framework installed or the .NET framework is old.
-
Resolution
Install the supported .NET framework. .NET Framework 3.5 and up is required, and having both 3.5 and 4.0 installed side by side is not only supported, but may be manditory to allow certain portions of the Spotlight Client to function properly.
