Updating from Revolution 4.0 to LiveCode 4.5

[Francis Nugent Dixon]

Hi from Beautiful Brittany,

I had a few months spare in my Run-Rev 4 licence,
so I downloaded LiveCode 4.5.0 (Happy Bunny !).

In order to ensure that LiveCode is called when I
double-click on a Revolution stack, I now have to
delete my folder Revolution Studio (or something of
that ilk).

But the folder contains a multitude of files, and
the LiveCode application is but one file.

Before doing something stupid, how do I proceed ?

Do I simply delete the Revolution.app in the Revolution
Studio 4.0 folder, and replace it by the new LiveCode
4.5.app ?

..... Or is it just a tad more complicated ?
