I finally got round to testing the latest installer of DVDFab, namely version 6.2.1.8. Goo dnews for those who did not get it running, or bad news for those who allready did what I just did and can't get it to install anyway.
Important is that you first install Internet Explorer 7 (do NOT install version 6 since that will NOT be enough) in a Windows XP bottle, if all goes well, this will automatically install Microsoft XML Parser 3.0 package (if not, then make sure you install that as well) and the Flash plugin. The flash plugin you don't need but it is installed anyway. After IE 7 has been installed, install DVDFab 6 ... I think the XML parser is required and the lack of this package together with IE 7 is causing an access violation. DVDFab installer just assumes these are installed by default. Weird, since it did not before and also did not need to. Installing only the XML parser package is not enough either (I tested it :) ).
