Problem
You cannot log on to the Web Client application after upgrading to Update 43 due to an error message:
An error occurred whilst communicating with client services or Client services failed to start
This warns that:
The app server requires ASP.Net Core Runtime Hosting Bundle.
Common Causes
You might encounter this problem because the ASP.NET Core Runtime Hosting Bundle pre-requisite is missing from the application server software.
Solutions
You must ensure all software pre-requisites are installed on the application server before upgrading. You can check the pre-requisites list in the HxGN SDx Hardware and Software Recommendations for your version of HxGN SDx.
As from Update 43, the ASP.NET Core Runtime Hosting Bundle is a required pre-requisite. Install any missing prerequisites, recycle your app pools, and try to log on again.
The installation setup will continue installing the product but a compatible version
of the ASP.NET Core Runtime Hosting Bundle must be installed and configured on the
application server before you can run the product.
