I have looked all over the place and have even been tempted to call Microsoft's tech support if they had one and could find the number.
But I can't imagine its that hard to turn on/enable .NET Framework. I am running XP Home. I have found the ways how to do it in Windows 7 and 8 and thought it might be similar for XP, not the case or maybe it is and just haven't found it or its buried somewhere. I thought something like the attached screenshot would be easy enough to find to do it and seems it is for 7 and 8. I've been told its easy as checking/unchecking a box.
Again the attached image is what I am hoping is what I have to find on my OS but I believe its from Windows 7, 8 or maybe Vista but not sure as I don't have any experience with them.
