Question with regard to the upcoming 1.05 update

[Crossroads]

To have a second copy do I have to run the installer again and select a different destination folder?

That's how I did it at least, to play it safe. Besides, I wanted a really really clean base install for testing. So I actually ran the installer twice, both installs to go under Matrix Games:

"C:\Matrix Games\John Tiller Campaign Series 1.04"
"C:\Matrix Games\John Tiller Campaign Series"

Then, shortcuts on my Desktop for both Main Menus.
