Jo, You have done nothing wrong. This message is probably from Windows 10 or your virus program. It is a warning that the installed program wishes to make changes to the program on your computer and must be agreed before the install can complete. This warning is only a concern when it comes up when you are NOT installing an update or program. I'm using Legacy 8 build 8.0.0.459 with no problems on windows10 Ian On 10-Jan-17 2:33:00 PM, Jocelyn<[email protected]> wrote: Hi I have just updated my Legacy to the latest update of December.
