Patching Firefox Installed Under User Hive

Hi all,

We have the latest version of the Firefox patch definition in the scan list but devices with older versions installed are not getting detected as needing the new update.  Checking the detection logic I find this:

strBackupKeyPath = "HKLM\SOFTWARE\Mozilla\Mozilla Firefox\CurrentVersion"

I checked the registry on one of the 'problem' systems and this registry does not exist.  So it looks like software was installed by the user and hence into the user hive. Anyone else seeing this?  Is the only alternative to create a custom def to maybe look for the executable on the device with a lower version rather than relying on the reg key?

Thanks
