Why am I unable to open the Splunk App for Windows Infrastructure on our Splunk Enterprise?
Here is a screenshot below of what I'm seeing.
Any help for this issue please?

Looks like your port 8000 is used by some other application. Try accessing splunk on a different port. Worked for me when changed to 8001. Restart not required.
Look for file web.conf under Splunk/etc/system/default
