Mark I just went to the control panel Uninstalla program and the and the MS Framework 4 or later isn't listed? Bernardo

It forms part of Windows 8 and 8.1 and is included in the list you see when you click on control panel\programs and features\ Turn Windows features on or off.
Windows 8 and 8.1 do not install it as default.
It doesn't appear in the list of installed programs.
I think I remember that in Windows 7 it did appear in the list.

Although the files are included in the download, they must be extracted into Windows after installation. Possibly, this has been done for you or the installation files have been added for you later.

If you try to use software that requires it, you will normally see a warning message, so if you don't have it installed and haven't seen any and everything works, I suspect you don't need it (yet).

However, my advice would be to leave the files where they are for future reference.
