Would like to use Windows Mail on a Windows 7 Pro PC. I see there is a folder all ready with the working files under c:\Program Files. The only problem is that there are .mui files for the needed program executable file and for the msoe.dll file. How do you make those two active? I know I can download Windows Essentials. But since the folder is all set up, why would I do that? What's the point of MS supplying all the files, but adding a mui extension? Thanks in advance for your help.
