I think the Zero G Installer was new with LW 2.7.9
For the most part it works good. I really like the fact that is does not wipe out our previous options and settings. No more rebuilding our Hosts filter list.
Only complaint: After installation, Zero G Installer leaves a bunch of files laying around. Such as a few in Windows Temp Folders, and sub folders, and also surprisingly a new Folder at C:\Program Files\Zero G Installer. I think this much trash left behind is sort of rude... if you make a mess, you should clean it.
