game not working

how can be possible that if game is exported it does not work on windows 7 with DX11.

It writes this: "you need the august 2008 directx update in order to run this application"

any ideas?

you need to install directx 9 on windows 7 (it's not included by default)

What I don't understand:

I sent a game to a friend, a simple .exe with no instructions whatsoever. The next day I asked if there were any problems. Answer: "No, started the application, it wanted me to install something, I agreed, and the game runs nice."

Could it be that often people just ignore the window that tells to install that needed files?

thanks, i have another problem. publisher told me, that he has dx11 and it should be forward-compatible and they are worried to reinstall it :(

is it possible to convert game to dx10 or dx11?

On vista/windows 7 the target computer (on which the game will be played) HAS to install DX 9.c.

So no, no converting.

Also, having DX9 and a more recent version installed in parrallel should not cause troubles.
