Various forums tell you that all you need to do is to copy the cProgram Files\Windows Mail files/folders from Vista to Win 7 (after saving the current contents in case it goes pear-shaped). But I can't make this work. If I copy the files from 32-bit Vista to the cProgram Files\Windows Mail folder on 64-bit Win 7, WinMail.exe spawns loads of "Windows Mail *32" processes which consume vast amounts of memory within about a minute. If I try copy them to cProgram Files (x86)\Windows Mail, there are permission problems: some of the existing files are owned by TrustedInstaller and even running Explorer as Administrator I can't set permission to delete/overwrite them. Running WinMail.exe from a different folder (eg copy everything to a folder in my Documents folder) the processes run (there's a WinMail and a WinMail *32 process showing up in Task Manager) but no splash screen or window opens. What am I doing wrong? Is it there any way of running the 32-bit version of Vista's Windows Mail on a 64-bit version of Windows 7? If I were able to run it, what restrictions are there? Some sites suggest that it can't be made the default MAPI client for Mail and News, which isn't a show-stopper, but is there anything else? I loathe Windows Live Mail - it looks like a toy, with its pastel colours, its lack of dividing lines and lack of +/- boxes on nested folders etc. And I don't like having separate Inbox, Sent Items and Deleted Items for each mail account. I've looked at Turnpike but that has the same issue of separate folders for each account and, even worse, won't allow you to export/import multiple mail messages as eml files to allow messages that have been sent on one PC (eg a laptop) to be blended into the Sent Items folder on another PC, either by attaching them to an email or else by copying them as .eml files to a shared drive or removeable drive.
