We have 10.5.6 running with V3 with an XP Boot Camp on a separate hard drive. Apart from issues openin some outlook attachments it all seems to work ok. On installing V4 and selecting the Boot Camp XP it begins the conversion and fails at the end with the unable to write to the target drive, permissions... etc etc message. I've read the threads I can see, however they don't seem to refer to this specific scenario
