Qlik Web Connector Service does not start even though .NET Framework 4.8.1 is installed

Hello everyone,

I want to update Qlik Web Connectors to Version July 2025. I did everything according to https://help.qlik.com/en-US/connectors/Subsystems/Web_Connectors_help/Content/Connectors_QWC/Setup-d....

But when trying to start the service, I get the error 

Windows could not start the Qlik Web Connectors service on Local Computer.
Error 1053: The service did not respond to the start or control request in a timely fashion.

Information/Things I've done

  • I unblocked the ZIP-File before extracting the files
  • The OS is Windows Server 2022
  • .NET Framework 4.8.1 is installed (I checked in Registry Editor at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full, Release = 533325)
    • There are subfolders 1031 and 1033 for German and English language respectively, the Release in 1031 is still 528449, I don't know if that could be a problem
  • I reinstalled the service using the batch file of the new version
  • Installed current Visual C++ Redistributables (2015-2022)
  • Tried to start the QlikWebConnectorsSVC.exe manually

The error messages in Event log are the following:

Does anyone have an idea what else I could try? 

Thank you and regards

Hello everyone,

the problem was that in the config file I had

<RequireSSL>true</RequireSSL>

but also

<AllowRemoteAccess>false</AllowRemoteAccess>.

This combination does not work! I changed it to

<AllowRemoteAccess>true</AllowRemoteAccess>

and now the service starts.

Hello @Maike151 

follow this
https://help.qlik.com/en-US/connectors/Subsystems/Web_Connectors_help/Content/Connectors_QWC/Adminis...

 

once the service is created, change the user that runs the service to an user that is part of admin group and that is allowed to run services.

 

also, if im not mistaken, QlikWebConnectorsSVC.exe  cant be runned manually, for that, you need to use QlikWebConnectors.exe

 

Hope this helps.

Best,
