Im trying it now to Install on 2.5, the biggest effect on 3rd party scenery software is the relocation of the Terrian.cfg in ver 2.5. Before the Terrian.cfg was in the P3d root folder. Now it is located in
C:\programData\Lockheed Martin\Prepar3D v2\. My theory is I uninstall 2.4, Do a fresh clean install of 2.5 and then install FSGlobal 2010, first.... However before i install FSG2010 I am going to copy the terrian.cfg from its new
location back to Prepar3d root folder. Complete the install and when FSG is done i am going to cut and past the terrian.cfg back to its new location and hope for the best. It should work.
