My Blend Opens In game modelike it is like all the windows merged together only the top part with the x to exit is left i have been able to open the not in game version but I have to open blender and then select it to open threw it rather than just selecting the file from its location directly.
Open the file from blender, then turn autostart of in the game/runtime settings of the blend file then save it. Now when you open the blend anywhere else other than from within blender itself, it will open blender and not the runtime.
