Can't install iTunes

[unplanned bacon]

I had iTunes installed, then created a new account in Windows, deleted my old account and iTunes broke. I uninstalled it, tried again and it errored every time I tried to open it (it wouldn't list itself as an installed program). Then I tried again and the icon did nothing when I clicked on it, but it was listed in programs. I then force uninstalled it eventually to get rid off all traces and tried again. Now Windows Installer errors out saying

he feature you are trying to use is on a network resource that is unavailable"

I cannot get it to install at all now

Using Windows 8

I've tried MS Fix It, but I don't know the product code it's asking for. There are 3 name not available's in the registry though according to Fix It

I like Bacon

have you tried a older version of ITunes?

How do I get an older version? What's the current one first of all?
