BarTender Integration Service - No connection could be made because the target actively refused it
I am currently assisting with updating an install of BarTender 2019 to 2022. Everything was working prior to the update.
Under the Integrations > Deployments screen we see the following error:
The BarTender Integration Service must be running to deploy integrations. Please verify that the service is running and try again.Details: One or more errors occurred. An error occurred while sending the request. Unable to connect to the remote server No connection could be made because the target machine actively refused it 127.0.0.1:5159
Under the Windows Services tab we can see that BarTender Integration Service is running with a green indicator next to it. I think that the service is running but for some reason it can't be connected to.
We have tried restarting the Integration Service, restarting the app, closing the app and opening it again with Run as Administrator, and restarting the computer. We also checked under Windows Firewall and verified that a rule exists to enable access to port 5159.
At this point we are not sure what else to try. Has anyone experienced this issue and know of a fix?
It seems that this problem can be resolved by installing the .Net Web Hosting bundle. https://dotnet.microsoft.com/en-us/download/dotnet/5.00
