I presume FH v.4.2 was a slip of the keyboard, and you mean FH v.4.1.3. Anyway, you will need to install the FH full v.4.0 and then upgrade to FH v.4.1.3. Are you a new FH user, or are you migrating from an existing Windows PC ? Have a look at the FHUG > Knowledge Base > Family Historian Installation Guide, especially how to Move Family Historian Settings.

I have ordered Paralells 7 and will be installing XP Professional Service Pack 3. I would like to know if their are any pitfalls to look out for during installation of Paralells and XP, Also the installing of FH v.4.2. John
