From the log I found:
Action 19:05:38: PostInstallScripts. Importing Lookupservice data...
CustomAction DoUpdateAndMigrateTasks returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 19:05:39: InstallFinalize. Return value 3.
Did you tried the workaround from this KB article: Upgrade from vSphere 5.1 to vSphere 5.5 rolls back after importing Lookup Service data (2060511)
