[xwiki-users] upgrade problem to 4.5.1 (Distribution Wizard)

Hello! I have a problem on the upgrade 4.4.1 --> 4.5.1. After login to the upgraded XWiki I stuck in the Distribution Wizard. On instance is reporting: "Installed version 4.4.1 is not valid" The other instance is reporting: "Installed version 4.2 is not valid" Any hints how to fix this?
