There is a report for fixlet 1105311 being false positive. Maybe I know what kind of failure happened in your environment?
If possible, can you provide the fixlet evaluation result and following registry keys for investigation?
"HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based
Servicing\Packages"
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer"
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
