errrr

I think I answered my own question. I have a retail version of XP Pro, not the Corporate version. For test purposes, I googled a corporate version key and tried that. It worked perfectly - so I guess you just have to make sure that you have the correct version and key - makes sense from MS's point of view as unattended installs are presumably intended for commercial deployment rather than home use (I am just very lazy). Such is life I suppose

I have the same problem, everything else automates fine but it asks for the XP serial number every time. I have tried with and without quotes but makes no difference. Are some keys blocked because of a licemce restriction or something? One thing I would suggest to The_Flying_Scot is that you download a copy of MS Virtual PC - its free for 45 days and you can test your installations without making all those coasters - http://www.microsoft.com/downloads/details...&displaylang=en . I would really appreciate any advice on this as it extremely frustrating . Thanks.
