Troubleshooting
Problem
On some Windows systems, using Update Installer 11.7.1.033 or later to apply a patch or fixpack in GUI mode leads to an HTTP 500 error window in the web browser with a NumberFormatException.
Symptom
The failure is intermittent. Sometimes it happens when the user clicks the "login" button in the startup panel, or when the "Next" button is used to move from one panel to the next. The most frequent occurrence is in the Microservices upgrade panel, when checking the checkbox to update the path to the Microservices repository. It has also been seen in the panel used to install a new Microservices tier, when scrolling the window with the scroll bar.
In all cases, the browser display of the Update Installer user interface is replaced by an HTTP 500 error window containing an error that looks like this:
