https://community.splunk.com/t5/Splunk-Enterprise/Splunk-Enterprise-Upgrade-Error/m-p/763031#M24540 <P>Upgrading from Splunk 10.0.0 to 10.4.1 on Windows server 2019 using the msi.&nbsp; The upgrade worked fine on one system then threw an error on the second system for missing splunk\share\mbtiles\splunk-tiles-dark.mbtiles. I canceled the install and it hung up while rolling back changes. After about 6 hours we ended the installer task. When we run the installer now, it acts like a first install, not an upgrade. I don't want to run it and wipe out all of our data and knowledge objects. Any suggestions?&nbsp;&nbsp;</P> Thu, 20 Aug 2026 16:26:16 GMT ATOM1 2026-08-20T16:26:16Z https://community.splunk.com/t5/Splunk-Enterprise/Splunk-Enterprise-Upgrade-Error/m-p/763031#M24540 <P>Upgrading from Splunk 10.0.0 to 10.4.1 on Windows server 2019 using the msi.&nbsp; The upgrade worked fine on one system then threw an error on the second system for missing splunk\share\mbtiles\splunk-tiles-dark.mbtiles.
