Nigel: it's not entirely clear what you want to achieve. Assuming you have your genealogy stored on an XP machine and wish now to transfer it to a Windows 7 machine. You must distinguish in your mind between THREE things that work together but are essentially separate. 1. Program files, such as FH itself (100% Calico Pie program, without any user data). 2. Settings that you may have set into FH in your current installation. Some FH users may use FH straight out of the box and will not have made any changes to FH settings. Settings carry user preferences, not personal information, they instruct the FH code on how you want it to respond. 3. Your user files of photos, documents etc and including the key Gedcom file containing your stored FH user data. There is no direct way to transfer the installation of FH itself from an XP machine to a Win7 machine. You'll have to get out your original FH installation discs and do a fresh install on your W7 machine. And check on the internet to see if there are updates from Calico Pie that apply to the version of FH in your installation DVD. The use of Microsoft "Easy Transfer" software may come to your assistance. I recommend you study the Microsoft URL: http://www.microsoft.com/download/en/details.aspx?id=4503 Microsoft don't guarantee it, but in many cases where application programs have had special settings inserted by users, the use of "easy transfer" will carry over from XP to Windows 7 the user settings. Make sure you first understand the sequence of events and then follow the instructions to the letter. You mentioned proof of ownership. As far as I know Calico Pie will not challenge your setting up FH on a new Windows 7 machine from your own original CDs, but the licence terms may well require you to uninstall the program on the old computer after you have successfully made the changeover. I'm pretty sure Calico Pie will require you to enter a Registration Key that should be found in the sleeve containing your FH product. Ian
