Qlik Web Connector service starts and then stops.

A pop-up error similar to the below is seen:

...one or more windows services were started and then stopped

along with the following in the Windows event logs from source QVSource:

Service cannot be started. System.UnauthorizedAccessException: Access to the path 'c:\QlikWebConnectors\App_Data\LicenceSettings.xml' is denied.
   at QlikWebConnectorsService.Service.OnStart(String[] args)
   at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)



Alternatively, the pop-up error displays:

"The Qlik Web Connectors service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs."

Along with the following registered in the Service_startup_log.txt:

1/4/2019 9:30:20 PM    OnStart:ERROR: APIConnectorInterfaces.Exceptions.QwcException: MULTIPLE_INSTANCES_NOT_PERMITTED
   at APIConnectorWeb.Services.Licensing.LicenceManager.StartupCheck(Action`1 startupLogger)
   at APIConnectorWeb.Startup.WebBaseBootstrap.StartCommon(String appRoot, String relativeConfigFilePath)
   at APIConnectorEngine.Qwc.BaseBootstrap.Start(Boolean isService)
   at APIConnectorEngine.Qwc.BaseBootstrap.StartServiceVersion()
   at QlikWebConnectorsService.Service.OnStart(String[] args)



Environment:

 

Cause:


For the two instances or the problem described respectively:

  1. After an upgrade the service account may have been set to Local system or changed from the original service account used.
  2. QlikWebConnector.exe may have been started in the environment or has been closed but is in hung state.

 

Resolution:


For the two instances or the problem described respectively:

  1. Make sure the service account has access to the necessary Qlik Web Connector installed files.
  2. Make sure that no other QlikWebConnector.exe instance is running (under the same or different user) or hung. Check in task manager for other instances.
