Hi Steve,
I was testing version 2.7 and I think it's not working the way it suppose to be. That is handling both FSX and FSX SE installations at the same time not needing to uninstall / install the libraries each time I use one Sim or the other one. In the way it is implemented only one Sim at a time works with DX10 Scenery Fixer.
Hope I was clear enough.
Kind regards.
