Thanks! I had seen that post, but Splunk support did not want to provide me with the 0GB/day license that enables KV Store. They kept telling to contact the developer of the Add-on and that they didn't support it. That using the Forwarder Group license should be all I need.
I did, in my haste, try the Free License and that worked. Finally support suggested I copy the enterprise 0GB/day license they provided 2 years ago on another heavy forwarder to this one and that worked too (I should have thought about that before them).
Not sure why this add-on is not working with the normal Forwarder Group License on a Heavy Forwarder, I feel like it should.
