Hello,
I just proceed to upgrade my forest pro from the 5.4.1 to the latest 6.1.1 (I need to clarify that first I uninstalled the old version), after installing the new one and running and downloading the assets with the update manager, I went to do my first test and tried to add one of the new Layered lawns. First I got a prompt asking to add the map's path in the external files and when I click to add the paths automatically I got an error message that couldn't find the full.bmp so I opened win explorer and tried to navigate to the path in question and found the Itoo Software folder from Program Files (x86) doesn't exist anymore, the folder now it's in Program Files.
So that creates a problem since all my projects are pointing to the (x86) folder and apparently, even the preset libraries are so whatever I try to add will have missing textures.
