I have a client with a new PC running 64-bit Win 7 Home Premium - SVC Pack 1 (I think), with Mozilla Thunderbird 3.1.9 installed and running well.

The old server that was replaced, 32-bit Win XP, had Netscape Communicator 4.8 installed and running, and there are some old SENT Emails and TEMPLATES that they need to import into Thunderbird. However, just copying the entire old directory, including all the data and folders, to the new machine doesn't work. I'm sure it's because Netscape hasn't actually been installed and updated the Registry, etc., for file locations. Even worse, I d/l'd the Netscape 4.8 installation program, but it won't install under the 64-bit version of Windows.

I've tried installing it running Windows XP compatibily settings, but this also fails. Any work-arounds come to mind? Knowing that 4.8 ran under XP, I'm surprised that I can't install it with XP compatibility mode.
